Phidippus regius, the regal jumping spider, is the single most popular jumping spider species in the pet hobby. Native to the southeastern United States, the Caribbean, and parts of Central America, it combines manageable size, a calm and curious temperament, wide morph availability, and straightforward husbandry into a package that works for first-time keepers and experienced hobbyists alike. This guide covers everything specific to P. regius care, from enclosure setup and the named regional morphs (Soroa, Bahama, Apalachicola, and more) through feeding, handling, molting, breeding, bioactive enclosure options, and the six most common health issues. If you are still deciding whether the species is right for you, our overview on jumping spiders as pets covers the bigger picture first.
Taxonomy and Classification
Phidippus regius belongs to the family Salticidae, the largest family of spiders, with over 6,300 described species worldwide. Within Salticidae, it sits in the genus Phidippus, a group of about 60 species native to North and Central America, all characterized by relatively large body size, iridescent chelicerae, and bold coloration. The species was first described by German arachnologist Carl Ludwig Koch in 1846. The species name “regius” translates from Latin as “royal” or “regal,” a reference to its size and striking appearance compared to other North American jumping spiders (source: Animal Diversity Web).
Other commonly kept Phidippus species include P. audax (bold jumping spider), P. otiosus (canopy jumping spider), and P. johnsoni (Johnson jumping spider). Among these, P. regius is the largest, most widely bred in captivity, and most commonly available through online breeders and pet stores. For a direct husbandry comparison with the next most popular species in the genus, see our Phidippus audax care guide.
Geographic Range and Wild Habitat
In the wild, P. regius is found throughout the southeastern United States, with Florida as the core of its range. Populations extend north through Georgia and the Carolinas, west along the Gulf Coast to Mississippi, and south through the Florida Keys into the Bahamas, Cuba, Jamaica, and other Caribbean islands. Introduced populations have been documented in parts of coastal Central America (source: BugGuide).
Within its range, P. regius occupies a variety of habitats: palm tree bark, wooden fences, building exteriors, citrus groves, and the edges of subtropical woodland. It is not a deep-forest spider. It prefers semi-open environments with sun exposure, vertical surfaces for hunting, and crevices for retreat construction. This preference for structures and human-adjacent habitats is part of why the species adapts so well to captivity, the enclosure mimics the kind of vertical, sheltered microhabitat it would naturally seek.
Seasonal behavior in wild populations varies by latitude. In central and southern Florida, P. regius remains active year-round. In the northern parts of its range (the Carolinas), activity slows during cooler months and spiders may enter a semi-dormant state in sheltered retreats until spring temperatures return.
Species Profile
Adult Phidippus regius measure 12 to 22 mm in body length (females larger than males), live 1.5 to 3 years for females and 9 to 15 months for adult males, and thrive at 72 to 82 degrees Fahrenheit with 50 to 60 percent ambient humidity in a 4 x 4 x 7 inch vertical enclosure minimum. The species is calm, diurnal, beginner-suitable when its specific welfare parameters are met, and the largest jumping spider commonly kept in the hobby.

P. regius is the largest commonly kept Phidippus species and one of the largest jumping spiders native to North America. Its size makes it easier to observe, feed, and handle than smaller species, which is a significant part of its appeal to new keepers (source: BugGuide). For a full breakdown of how it stacks up against other beginner-suitable species, see our roundup of the best jumping spider species for pets.
Color Morphs and Identification
One of the most attractive aspects of P. regius for hobbyists is its range of captive-bred and regional color morphs. Selective breeding over the past decade has produced distinct visual varieties tied to specific founder populations, so morph names usually reference geography (Soroa, Bahama, Apalachicola) rather than a single genetic locus. Identification can change as the spider molts toward maturity, so the morph label only stabilizes after the final molt.
Standard (Florida wild-type): Black cephalothorax and abdomen with white or cream markings. The wild-type coloration most commonly seen in mainland Florida populations.
Bahama / leucistic morph: Predominantly white body with reduced dark markings, originally line-bred from Bahamian founder stock. One of the most sought-after morphs, often commanding $80 to $200+.
Soroa (orange) morph: Vivid orange to peach coloration on the abdomen and sometimes the cephalothorax. Named after Soroa, Cuba, where the founder population was collected. The orange tone is most intense in females.
Apricot morph: A paler, pastel variation of the orange line. Less common and typically priced higher than standard Soroa.
Other named lines: Apalachicola, Rastafari, Everglades, Dos Gardenas, and Isla de la Juventud appear on breeder platforms like MorphMarket. Many of these represent regional founder populations rather than confirmed polygenic traits, and color expression can drift across generations.
Males of all morphs display iridescent green or blue-green chelicerae (fangs/jaws), which are prominently used during courtship displays. Female chelicerae are less colorful but still visible. Sex can be distinguished from the sub-adult stage: males develop enlarged, bulbous pedipalps and often show more vivid chelicera coloration (source: Bantam Earth). For a step-by-step sexing walkthrough with photos, see our guide on how to sex a jumping spider.
Enclosure Setup for P. regius
A correct P. regius enclosure is vertical (taller than it is wide), at least 4 x 4 x 7 inches for an adult, has cross-ventilation on two opposing sides, sits at 72 to 82 degrees Fahrenheit and 50 to 60 percent humidity, and provides cork bark, vines, and a broad ceiling surface for retreat construction. The four core husbandry parameters covered below (size, ventilation, substrate, climate) are the difference between a thriving regal and a stressed one.
Enclosure Size and Type
Adult P. regius need a vertical enclosure measuring at least 4 x 4 x 7 inches. Front-opening acrylic or glass terrariums are preferred because they allow access without disturbing the spider’s retreat web, which is typically built near the top of the enclosure. Top-opening enclosures work but require reaching past the retreat to access the interior. For a deeper dimensions breakdown by life stage, see our jumping spider enclosure size guide.
Slings (spiderlings) start in small deli cups (3 to 4 ounce) with ventilation holes punched in the lid and a small piece of crumpled paper towel for a retreat anchor. Upgrade to a larger container at each molt as the spider grows. Most keepers transition to the adult enclosure when the spider reaches the fourth or fifth instar. Our complete walkthrough on jumping spider enclosure setup covers layout choices in detail.
Ventilation
Cross-ventilation is essential. Stagnant air promotes mold growth on prey remains and can stress the spider’s respiratory system. Enclosures with mesh panels on at least one side and either the top or opposite side provide adequate airflow while maintaining humidity. Avoid fully sealed containers even if you mist frequently (source: Josh’s Frogs).
Substrate
Use 1 to 2 cm of coconut fiber (coco coir) as a base substrate. Coco coir retains moisture for ambient humidity, resists mold better than peat, and is safe if accidentally ingested. Sphagnum moss placed in one corner creates a humidity gradient. Avoid sand, gravel, or vermiculite, which can clog the spider’s book lungs. For a side-by-side comparison of substrate options and how to layer them, see our best substrate for jumping spiders guide.
Decorations and Climbing Structures
P. regius is arboreal and needs vertical surfaces to climb and hunt from. Provide:
- Cork bark pieces (flat or round) positioned vertically against the enclosure walls
- Artificial vines or branches for climbing routes between surfaces
- Small silk or live plants (pothos cuttings work well in humid conditions) for additional anchoring and visual barrier
- A broad surface near the top (leaf, cork bark ledge) where the spider will likely build its primary retreat
Experienced keepers we work with find that providing multiple retreat options near the ceiling results in the spider choosing the one it prefers and using it consistently. The retreat location becomes the spider’s “home base” for resting, molting, and egg-laying. For enrichment beyond the basic decor layout, our jumping spider enrichment guide covers climbing structures, novel objects, and visual stimulation.
Bioactive Setup Option
Experienced keepers sometimes run P. regius bioactively, with a drainage layer of bio-balls or lightweight expanded clay aggregate, a barrier of mesh, three to four centimeters of an arboreal-blend substrate (coco coir, sphagnum, leaf litter, charcoal), live pothos or fittonia cuttings, and a small springtail and dwarf isopod cleanup crew. The benefit is self-regulating humidity and waste breakdown; the trade-off is harder visual inspection of the spider and slower troubleshooting if husbandry goes wrong. Bioactive is not necessary for a healthy regal and is best attempted after one or two successful conventional setups. Whichever route you choose, follow our jumping spider enclosure cleaning guide for spot-cleaning cadence (weekly prey-remains removal) and full substrate refresh timing (every two to three months for non-bioactive, six to twelve months for bioactive).
Temperature
P. regius thrives at 72 to 82 degrees Fahrenheit (22 to 28 degrees Celsius). This species tolerates a wider range than many exotics, but sustained temperatures below 65 degrees Fahrenheit slow metabolism, reduce appetite, and increase the risk of molting complications. Temperatures above 88 degrees Fahrenheit cause heat stress and rapid dehydration.
Most homes provide adequate temperature without supplemental heating. If your room regularly drops below 70 degrees, a small heat mat placed on one exterior wall (not underneath the enclosure) with an adjustable thermostat provides a gentle warm zone. Never use heat lamps on a small enclosure; they overheat the air volume too quickly (source: The Tarantula Collective). Our dedicated jumping spider temperature and humidity guide covers the full thermal physiology including night-time drops, seasonal adjustments, and what hygrometer placement is reliable.
Humidity
Target 50 to 60 percent ambient humidity. Achieve this by misting one corner of the enclosure lightly every two to three days. The spider drinks from water droplets that form on the glass and plant surfaces. Avoid saturating the substrate or creating pooling water, which promotes bacterial and mold growth.
During premolt (when the spider stops eating and becomes less active), slightly increasing misting frequency to maintain humidity near the upper end of the range helps prevent stuck molts. Some keepers place a damp sphagnum moss pad near the retreat during premolt. For more on droplet-based drinking behavior and signs of dehydration, see our jumping spider hydration guide.
Lighting
P. regius is diurnal and uses visual cues to hunt, so it needs a clear daily light-dark cycle but does not need specialized UVB lamps. Ambient room light or a nearby desk lamp on a 12-hour timer is sufficient. Direct sunlight is dangerous because it overheats the small air volume; place the enclosure within visual range of a window but not in the direct beam. See our jumping spider lighting guide for the full UVB-versus-ambient-light breakdown.
First Week After Acquisition
When a new P. regius arrives, place it in its final enclosure, mist lightly, and then leave it alone for five to seven days. Do not handle, do not feed for the first 48 hours, and minimize visual disturbance. Offer one appropriately-sized prey item on day three; if refused, remove the prey and try again two days later. New arrivals routinely refuse the first one or two feedings while they map their new environment and build an initial retreat. By the end of week one, most regals are eating normally and beginning to track movement outside the enclosure.
Feeding P. regius
Feed P. regius live invertebrate prey no larger than its abdomen, with frequency scaled to life stage: slings every one to two days on fruit flies, juveniles every two to three days on larger flies or pinhead crickets, and adults every three to five days on crickets, blue/green bottle flies, or the occasional waxworm. Gut-load feeders 24 hours before offering, and rotate prey types to broaden the nutritional profile.
Prey Items by Life Stage
| Life Stage | Primary Feeders | Size Rule | Frequency |
|---|---|---|---|
| Sling (1st-3rd instar) | Drosophila melanogaster (small fruit flies) | Smaller than abdomen | Every 1-2 days |
| Juvenile (4th-6th instar) | D. hydei (large fruit flies), pinhead crickets | Body-length or smaller | Every 2-3 days |
| Sub-adult/Adult | Small crickets, waxworms, mealworms, blue/green bottle flies | No larger than abdomen | Every 3-5 days |
The universal feeding rule for jumping spiders applies to regals: never offer prey larger than the spider’s abdomen. Oversized prey can injure the spider or cause enough stress to trigger a premolt fast. For a deeper breakdown of feeder choice, sourcing, and culturing, see our guide on best feeder insects for jumping spiders and the species-by-species feeding schedule by age.
Gut-Loading and Nutrition
Gut-loading feeder crickets with fresh carrot, sweet potato, or leafy greens 24 hours before offering them to your spider improves the nutritional profile of the prey. Fruit flies raised on commercial culture media are generally nutritionally adequate but less varied than gut-loaded crickets.
Rotating between two or three feeder types over the course of a month provides a broader nutritional profile than relying on a single species. For detailed feeder information, see our guide on what jumping spiders eat.
Feeding Behavior
P. regius is an active stalker-pouncer. When prey enters the enclosure, the spider will typically orient toward it (turning to face the prey with its large anterior median eyes), adopt a low stalking posture, slowly close the distance, and then launch in an explosive pounce. This hunting sequence can take anywhere from a few seconds to several minutes depending on the spider’s hunger level, the prey type, and the individual’s hunting style.
If your regal refuses food for more than a week outside of premolt, check temperature (too cold suppresses appetite), humidity (dehydration reduces feeding motivation), and prey size (too large triggers avoidance). A spider approaching senescence will also show declining prey interest, but this is a gradual process over weeks. Our diagnostic walkthrough for when your jumping spider won’t eat covers each cause in order of likelihood.
Handling P. regius
Regal jumping spiders are among the most handleable arachnid species, but handling is a privilege the spider extends, not a routine the keeper imposes. Many individuals become comfortable walking on their keeper’s hands within a few sessions, while a small minority remain consistently skittish. Read the spider’s body language before, during, and after every session, and keep sessions short and low.
Handling Technique
- Open the enclosure and place your open hand flat in front of the spider’s current position.
- Allow the spider to walk onto your hand at its own pace. Never grab, pinch, or scoop.
- Keep your free hand available as a “bridge” if the spider walks toward the edge of your hand. Gently redirect by placing the second hand in front of it.
- Handle over a soft surface (bed, carpet, couch cushion) to cushion any accidental falls.
- Keep sessions short: one to three minutes initially, extending as the spider becomes more comfortable.
Our complete jumping spider handling guide covers acclimation pacing, recovery between sessions, and how to safely move a spider that has bolted or jumped.
Reading Your Spider’s Behavior
A relaxed P. regius walks calmly, pauses to look at objects, and may “track” your face with its large forward-facing eyes by tilting its head. A stressed spider crouches low, raises its front legs in a threat posture, drops from your hand on a dragline, or repeatedly tries to jump away. Subtler stress signals include rapid palp-tapping, abdominal flagging (raising the abdomen above the cephalothorax), and refusing to step from one hand to another.
Vet-tech teams in the jumping spider community observe that the single biggest handling mistake new keepers make is persistence when the spider is displaying stress signals. If the spider crouches, raises legs, or tries to flee repeatedly, return it to the enclosure and try again in a day or two. Forced handling does not produce a calmer spider; it produces a more defensive one. Our jumping spider behavior guide goes deeper on body-language interpretation across species.
When Not to Handle
- During premolt (spider has stopped eating and is sluggish). Handling risks dysecdysis (stuck molt).
- Within 48 to 72 hours after a molt. The new exoskeleton is soft and vulnerable to damage.
- First week after acquisition. Let the spider acclimate to its new enclosure and build a retreat before introducing the additional stimulus of handling.
- If the spider is visibly carrying an egg sac. Gravid females should not be disturbed.
Molting in P. regius
Molting is how P. regius grows between hatching and adulthood, shedding the old exoskeleton inside a sealed retreat over several hours to a day. Slings molt every two to four weeks, juveniles less frequently, and the final molt produces the sexually mature adult. Premolt usually announces itself one to two weeks ahead with appetite refusal, reduced activity, and retreat reinforcement.
Premolt Signs
- Refusal to eat for several days to over a week
- Reduced activity, spending more time in the retreat
- Abdomen may appear darker or duller as the new exoskeleton develops beneath the old one
- Enclosure silk retreat may be reinforced or sealed with additional webbing
During the Molt
The spider seals itself inside its retreat and may take several hours to a full day to complete the molt. Do not disturb the retreat or attempt to observe the process. Remove all live feeder insects from the enclosure, as they can bite a vulnerable molting spider.
Post-Molt
The spider emerges with a soft, pale exoskeleton that hardens and darkens over 48 to 72 hours. Colors are often more vivid immediately after a molt. Do not offer food until the spider shows active interest in prey, typically two to four days post-molt. Do not handle until at least 72 hours after the molt. Our dedicated jumping spider molting guide covers stuck-molt rescue, post-molt water access, and how to tell when your spider has reached its final adult molt.
Breeding P. regius
Breeding regal jumping spiders requires two healthy, well-fed adults, separate enclosures until pairing, a brief and continuously supervised introduction (with the male placed into the female’s enclosure), and a plan for raising 50 to 200+ spiderlings from each successful egg sac. It is one of the most rewarding projects in the hobby, especially for keepers working with named morphs, but the spiderling logistics are non-trivial.
Sexual Maturity and Breeding Readiness
Males reach sexual maturity after their final molt, identifiable by their fully developed bulbous pedipalps. Females typically mature one to two molts after males of the same age cohort. For the best breeding outcomes, pair the male within a few weeks of his final molt, while he is healthy and active. Males in the later stages of their post-maturity lifespan may be less vigorous in courtship and less successful at mating (source: The Tarantula Collective).
Both male and female should be well-fed in the weeks before pairing. A well-nourished female is less likely to attack the male during introduction, and a well-fed male has more energy for the extended courtship display.
Courtship Behavior
The male P. regius courtship dance is one of the most elaborate displays in the Salticidae family. Upon detecting the female (often by chemoreceptive cues on her silk), the male raises his front legs, displays his iridescent chelicerae by spreading them wide, and performs a rhythmic side-to-side body vibration. He advances slowly, pausing to repeat the display if the female does not move toward him. The entire courtship sequence can last anywhere from a few minutes to over an hour.
A receptive female remains stationary, lowers her body posture slightly, and allows the male to approach and mount. An unreceptive female raises her front legs in a threat posture, lunges, or actively retreats. If the female shows any aggression, remove the male immediately. You can attempt pairing again in three to five days after feeding the female.
Pairing
Introduce the male into the female’s enclosure (never the reverse). The male will begin courtship immediately if he detects the female, displaying his chelicerae, waving his front legs, and performing a species-specific body vibration dance. A receptive female will remain still and allow the male to approach. An unreceptive or hungry female may attack the male.
Watch the pairing continuously. Remove the male immediately after mating is complete or if the female shows aggression (lunging, threat posture). Male P. regius are frequently cannibalized during or after mating if not separated promptly (source: Exotics Source).
Egg Sac Timeline and Management
A successful mating produces an egg sac within two to four weeks. The female constructs a thicker silk retreat around the sac and guards it. During this period, do not disturb the retreat, move the enclosure, or attempt to handle the female. She may refuse food for part of this period, which is normal.
Egg sacs contain 50 to 200+ eggs depending on the female’s size, age, and nutritional condition. Incubation takes two to four weeks at normal room temperature (75 to 80 degrees Fahrenheit). Lower temperatures extend the incubation period. The female may produce multiple egg sacs from a single mating, spaced several weeks apart. Our standalone jumping spider breeding guide covers pairing logistics across multiple species.
Spiderling Rearing Stages
When spiderlings emerge from the egg sac, they remain clustered near the sac for the first one to three days while absorbing their remaining yolk reserves. After this initial period, they begin dispersing and will start hunting within days.
Separation timing is critical. Spiderlings should be separated into individual containers within three to five days of emergence. Cannibalism among siblings begins as soon as the spiderlings’ hunger exceeds their yolk reserves, typically by day three or four. Use small deli cups (2 to 4 ounce) with pinhole ventilation and a tiny piece of paper towel for a retreat anchor.
Feeding spiderlings: First and second instar spiderlings eat springtails and Drosophila melanogaster (wingless fruit flies). Offer food every one to two days. By the third instar, most spiderlings can take D. hydei (large fruit flies). For a full sling-rearing protocol see our jumping spider spiderling care guide.
Raising a clutch of 100+ spiderlings requires significant feeder insect supplies (springtail and fruit fly cultures) and many small containers. Most hobby breeders sell or rehome the majority of a clutch, keeping a small number for their own collection.
A single female can produce two to four egg sacs over her lifetime if well-maintained and re-mated or if the initial mating was sufficient. Each successive clutch tends to be slightly smaller than the first.
Wild-Caught vs Captive-Bred P. regius
Captive-bred P. regius is the standard recommendation for almost every keeper: known age, known morph lineage, parasite-free, and already adapted to enclosure life. Wild-caught specimens are legally collectable in much of the species’ native range, cost nothing, and offer a hands-on field experience, but they carry parasite risk, unknown remaining lifespan, and a longer acclimation curve. The two paths suit very different keeper profiles.
Captive-Bred (Recommended)
Captive-bred spiders are the standard recommendation for most keepers. They are raised in controlled conditions, free from parasites and pathogens found in wild populations, and already accustomed to enclosure life. Captive-bred specimens are available in specific color morphs with known lineage, which matters for breeders targeting particular traits. Reputable breeders also provide approximate hatch dates and instar stage, so you know the spider’s age and expected remaining lifespan.
The main drawback is cost. Captive-bred morphs like Bahama (leucistic) or apricot can run $40 to $200+, while standard wild-type specimens cost $15 to $30 from breeders on platforms like MorphMarket. For sourcing logistics, see our guides on where to buy a jumping spider and how much jumping spiders cost.
Wild-Caught
Wild-caught P. regius are free if you live in the species’ native range and know where to look, palm trees, fence posts, and building exteriors in Florida are productive spots. Some keepers enjoy the experience of finding and collecting their own spider.
However, wild-caught specimens carry real risks. They may harbor internal parasites, mites, or bacterial infections not visible on inspection. Their age and reproductive history are unknown, so a wild-caught adult female may be near the end of her lifespan. Wild-caught spiders also tend to be more skittish during the initial acclimation period, having never encountered enclosure life or human handling.
If you do collect a wild P. regius, quarantine it in a clean, simple enclosure for at least two weeks before introducing it to your permanent collection. Watch for signs of parasites (mites on the body, abnormal feces, persistent lethargy) and treat the spider as potentially carrying pathogens until it has settled in and fed normally through several feeding cycles. Our guide on catching wild jumping spiders covers ethics, technique, and legal considerations in depth.
Legal note: P. regius is not protected under any US federal or state law, and collecting wild specimens in its native range is legal on private property with permission. Do not collect from state or national parks without verifying local regulations.
Common Health Issues in P. regius
The six most common P. regius health issues are dehydration, dysecdysis (stuck molt), mites, oral nematodes, abdominal rupture from falls, and fungal infection from chronic over-humidity. Most are husbandry-driven and resolve with parameter correction; nematodes and severe fungal infection require an exotic-animal veterinarian. Always handle over soft surfaces, mist on a schedule rather than impulse, and quarantine new arrivals for two weeks to keep infestation pressure low.
Dehydration is the most frequent health issue. Signs include a shriveled, wrinkled abdomen and lethargy. A dehydrated spider may also stop eating even when prey is available. Increase misting frequency and ensure fresh water droplets are available on enclosure surfaces. In severe cases, place a damp cotton ball or sphagnum moss pad near the spider’s retreat to raise local humidity.
Dysecdysis (stuck molt) occurs when humidity is too low during premolt. If the spider appears stuck in its old exoskeleton, gently increase humidity by misting near (not directly on) the spider. Do not attempt to manually remove the old skin, pulling at shed exoskeleton can tear the soft new cuticle and cause fatal injuries.
Mites are small parasites introduced through contaminated substrate or feeder insects. White or reddish dots moving on the spider’s body or in the enclosure indicate a mite infestation. Quarantine the spider in a clean container with paper towel substrate and replace all enclosure contents. Grain mites from feeder cultures are the most common source; keeping feeders in sealed containers with fresh media reduces this risk. Our jumping spider parasites and mites guide covers prevention and treatment in depth.
Oral nematodes occasionally affect P. regius, particularly wild-caught specimens. Signs include visible thread-like worms near the chelicerae or in the oral cavity, reduced appetite, and lethargy. There is no established home treatment. Consult an exotic veterinarian if you suspect nematode infection.
Abdominal rupture can result from falls during handling or from impacts inside the enclosure. Even a fall from hand height (3 to 4 feet) onto a hard surface can rupture the abdomen. The hydraulic pressure system that powers jumping spider legs makes them particularly vulnerable to blunt impact. Always handle over soft surfaces and keep sessions short.
Fungal infections appear as cotton-like white patches on the body or legs, distinct from the normal white markings of the species. Fungal issues typically arise from chronically excessive humidity combined with poor ventilation. Improve airflow, reduce misting frequency, and quarantine the affected spider. Severe fungal infections are often fatal.
Senescence decline is the natural aging process, not a treatable illness. An aging P. regius gradually loses coordination, stops hunting actively, and may have difficulty climbing smooth surfaces. Females in their final months may produce one last egg sac before declining. There is no intervention for age-related decline; provide comfortable conditions and easy access to water.
If your spider shows symptoms that do not resolve with husbandry adjustments within 48 to 72 hours, consult an exotic-animal veterinarian. For a broader symptom checklist, see our jumping spider health signs guide, and for the foundation husbandry context that underlies all of these issues, our jumping spider care guide covers the basics in one place.
Frequently Asked Questions
The questions below are the ones P. regius keepers ask most often after the initial care decision is made. Each answer is intended to stand on its own as a quick reference, with deeper coverage in the linked sibling guides where useful.
How big do Phidippus regius get?
Adult female P. regius reach 15 to 22 mm in body length, while adult males remain smaller at 12 to 18 mm, making this the largest jumping spider species commonly kept in the pet hobby. Size varies by individual genetics and nutrition during development, with well-fed captive specimens reliably reaching the upper end of the range. Females are consistently larger than males across all populations, including the Florida mainland and the Caribbean island morphs (source: BugGuide). Size becomes obvious from the sub-adult stage, which is also when sex differences in pedipalp shape and chelicera color become reliable.
How long do regal jumping spiders live?
Female P. regius typically live 1.5 to 3 years in captivity, while males live 9 to 15 months after their final molt because they invest heavily in courtship and mating rather than long-term survival. The longest-documented regal on record is a female at the Bronx Zoo that lived four years and nine months, far above the species average, attributed to stable temperature, abundant feeders, and minimal handling stress. Captive lifespan typically exceeds wild lifespan by six to twelve months because predation pressure is removed. For the full lifespan dataset across jumping spider species, see our jumping spider lifespan guide.
What is the best morph for beginners?
Any morph of P. regius is equally suitable for beginners because care requirements are identical across all morphs; the welfare parameters do not change with color. Standard Florida wild-type morphs cost the least ($15 to $30), are the most widely available, and tend to be the hardiest because the captive line is largest and most genetically diverse. Choose your morph based on visual preference and budget rather than perceived difficulty, and source from a reputable captive breeder so you know hatch date and lineage. Premium morphs are visually striking but do not change the underlying husbandry needs.
Can I house a male and female together?
No. Male and female P. regius must be housed individually and only placed together for a brief, continuously supervised breeding introduction, then separated immediately afterward. Permanent cohabitation reliably results in one spider killing and eating the other, regardless of how well-fed they appear at the start. The species is solitary in the wild as well; even in dense populations, adults occupy separate retreats. Cohabitation is not stress-free social pairing for these spiders, it is a fight delayed by ambient food availability. Always plan for one enclosure per spider, including for clutch separation.
Do regal jumping spiders need UVB lighting?
P. regius does not require UVB lighting for vitamin D synthesis or any other physiological function, unlike most reptile species. What they do need is a clear day-night cycle and enough ambient visible light to drive their diurnal hunting behavior. A well-lit room or a small desk lamp on a 12-hour timer is sufficient. Avoid placing the enclosure in direct sunlight, which overheats the small air volume rapidly and can cook the spider in under an hour. A consistent timer-driven cycle (12 hours on, 12 hours off) helps the spider settle into a predictable feeding rhythm.
How do I tell if my P. regius is male or female?
Males develop enlarged, bulbous pedipalps (the small appendages flanking the chelicerae) starting at the sub-adult stage, shaped like tiny boxing gloves. They also tend to be smaller overall, have more vividly colored iridescent chelicerae (often bright blue or green), and develop distinctive courtship markings on the front legs. Females are larger, rounder in the abdomen, and have slender pedipalps without the bulbous tip. Reliable sexing is possible by the fourth or fifth instar in most individuals, and the final molt confirms sex definitively. Slender palps plus a rounded abdomen at the final molt indicate female.
