Know your Brilliant Jumping Spider
Listing identity: Phidippus clarus – Brilliant Jumping Spider
Protect upper silk retreats, provide usable perches and size all vents and prey to the actual instar. Do not assume all Phidippus have the same climate profile.
The principles below apply alongside the individual notes above; size, maturity, locality and established stock history can change the details.
Build the stronghold
A refuge suited to this animal
Use a ventilated enclosure with secure upper perches and small, escape-resistant vents. A side or front opening helps preserve hammocks built near the top. Provide a normal day–night cycle and bright indirect light; direct sun can overheat a small container.
Use clean materials without pesticide or fertilizer contamination. Secure heavy furnishings before adding substrate, prepare the enclosure before arrival and size all gaps to the smallest animal you will house.
Balance the habitat
Water, moisture & temperature
Offer small drinking droplets on a wall or furnishing, allowing surfaces to dry between light mistings. Avoid soaking the spider or filling the enclosure with large droplets. Regius, audax, clarus and morpheus are not interchangeable climate profiles; confirm the conditions and life stage of the actual stock.
A humidity gauge measures air, not whether the retreat is structurally sound, desiccated or waterlogged. Inspect accessible substrate and water sources without destroying the animal’s refuge.

Feeding this animal
Offer captive-bred insects sized to the actual animal. Tiny juveniles need much smaller prey than adults. Adjust portions and intervals to body condition and feeding response; remove uneaten prey when refused and before a molt. Do not routinely feed vertebrates or leave dangerous prey loose with a vulnerable animal.
Offer captive-bred flies or suitably small feeder insects. Tiny juveniles require smaller prey and closer feeding checks than adults. Remove uneaten prey and avoid leaving crickets with a spider that has sealed itself into a retreat.
Give them quiet
Protect a vulnerable molt
Leave a closed premolt retreat undisturbed. Do not force food into a burrow, pull off old exoskeleton or move an animal that is shedding. Remove uneaten live prey. Resume feeding only after the new exoskeleton and feeding structures have hardened; recovery time varies with species and size.
Keep the watch
A steady keeper routine
Check enclosure security, water access and the animal’s condition each day without repeatedly opening its retreat. Remove accessible food remains, check for spoiled material and keep a record of meals, molts and changes. Spot-clean around established silk or burrows rather than rebuilding the whole enclosure unnecessarily.
House individually as the default and observe without handling. Secure lids and ventilation openings for the actual animal. Plan transfers within a controlled work area and protect delicate limbs, silk retreats and burrows from unnecessary disturbance.
Read the signs
When to review the setup
| What you notice | First checks |
|---|---|
| Food repeatedly refused | Check water, condition, maturity and signs of premolt; remove leftover prey rather than forcing a feeding response. |
| Refuge drying or flooding | Inspect the actual shelter and substrate. Adjust appropriate areas gradually while retaining ventilation. |
| Persistent weakness or injury | Record conditions and recent changes; seek an experienced exotic-animal veterinarian rather than attempting improvised treatment. |
| Escape or containment fault | Secure the room, protect others from contact and follow a planned, hands-off recovery procedure. |
From the keeper’s camp
Brilliant Jumping Spider FAQs
What enclosure does Phidippus clarus need?
Use secure upper perches and protect silk hammocks. A side or front opening helps avoid tearing a retreat during maintenance.
How should I manage water and temperature for Phidippus clarus?
Use the water and moisture section above alongside the actual stock’s successful routine. Measure conditions at the retreat, retain drinking access and ventilation, and account for life stage. Avoid changing the entire setup to chase a single air-humidity reading.
What should I feed Phidippus clarus?
Offer suitably sized captive-bred insects. Review portions and intervals against the animal’s size, body condition and feeding response; tiny juveniles need smaller prey. Remove refused prey rather than repeatedly trying to force a feeding response.
What should I do during a molt?
Keep the animal undisturbed, protect its retreat and remove uneaten live prey. Do not open a sealed burrow to check the molt or pull away old exoskeleton. Resume feeding after the new exoskeleton and feeding structures have hardened; timing varies.
Can I handle or house Phidippus clarus with another animal?
Use individual housing and observation as the default. A calm animal or a reputation for mild venom is not proof that handling is safe. Plan maintenance around escape prevention and the animal’s vulnerable molting period.
How do I check that I am using the right care sheet?
