About
The Red Skeleton (Burgundy Skeleton) - a wine-and-cream fossorial oddity from French Guiana: the "skeleton" leg striping of its genus over deep burgundy, and burrowing habits unusual for the otherwise arboreal spider-clade it belongs to. Its party trick is defensive: like all Ephebopus it carries Type V urticating hairs on its PEDIPALPS and flicks them into the face of anything leaning over the burrow - gloves and eye protection for deep cleans. Secretive, plug-the-burrow behaviour and a ferocious ambush feeding response. A rewarding display-of-nature species rather than a display spider.

Care Guide
Ephebopus rufescens
Red Skeleton - a complete husbandry sheet. Use as a starting point and adjust to your individual specimen.
What size enclosure does a Red Skeleton Tarantula need?
Adults
30 × 25 cm footprint with 12-15 cm of substrate - depth over floor space.
Slings & Juveniles
Small tubs with 6-8 cm of damp substrate and a starter hole.

What temperature and humidity does a Red Skeleton Tarantula need?
Heating
The Red Skeletons is comfortable at 24-28 °C. UK homes need supplementary warmth for much of the year; warm the room rather than the enclosure.
Humidity
75-85 %: keep the lower substrate consistently damp (never sodden) and overflow the water dish regularly.
Ventilation
Cross-ventilation with high humidity, fine mesh - the combination fossorials need.
What substrate is best for a Red Skeleton Tarantula?
Recommended Mixes
Depth
12-15 cm
Notes
The enclosure IS the substrate - deep, packed, damp-packed, holding burrows for years. Damp below, drier at the surface.
How do you set up a Red Skeleton Tarantula enclosure?
Décor
The Hide
Its own burrow, dug deep with a silk collar at the mouth - provide 12 cm+ of packed substrate and a starter excavation.
Water
Shallow dish at surface level - keep full and clean.
Lighting
Ambient room light only. Avoid bright spots and basking lamps.
How often should you feed a Red Skeleton Tarantula?
Good Feeders
Long refusal worrying you? Separate premoult fasting from genuine problems with our "Is my T okay?" checker.
Is my Red Skeleton Tarantula dying or moulting?
Pre-moult signs to look for
Refusing food for weeks is normal before a moult - a healthy Red Skeleton Tarantula fasting is almost never an emergency in itself. Watch for slowing down and spending more time in the hide, sealing the burrow entrance with silk (a sealed door usually means "do not disturb - moulting in progress"), laying a thick moult mat of web on the floor. New World species like this one often show a bald spot on the abdomen that darkens to near-black as the new skin underneath readies - a darkening bald patch is a reliable countdown, not a disease.
On its back is MOULTING, not dying
A Red Skeleton Tarantula lying upside down or on its side with legs curled inwards is almost certainly mid-moult. Do not touch it, do not right it, do not mist it - just remove any live prey (crickets can kill a defenceless moulter) and leave the room.
How long between moults?
For this species, expect a moult roughly every 21-42 days for spiderlings, every 50-85 days for juveniles, and every 120-190 days for sub-adults, with adult females moulting around every 9.3 months (up to 14 months at the extreme). Males never moult again after their ultimate (mature) moult.
After the moult: fang hardening time
The new exoskeleton stays soft, with fangs that cannot grip, for roughly 7 days in this species. Offer no food and no handling for about 7 days - feeding too early is how fresh moulters get injured. The shed exuvium is also the best sexing tool there is - see our tarantula sexing guide for what to look for.
Genuinely worried about behaviour that is not moulting? Our "Is my T okay?" triage tool walks the danger signs one by one.
What ongoing care does a Red Skeleton Tarantula need?
🪞 Moulting
Moults at the burrow bottom, usually behind a soil plug. Do not excavate. Keep humidity high and prey out; wait until it reopens and the fangs are black before offering food. Adult intervals apply to mature FEMALES - a mature male never moults again.
🧹 Cleaning
Weekly: refresh the water dish, clear boluses from the burrow mouth with tongs. Full clean rarely - every deep clean is a hair-flick risk.
✋ Handling
Not a handling species - skittish, fast, and armed with aimed urticating hairs. Catch cup only.
What are the most common mistakes when keeping Red Skeleton Tarantulas?
✓ What They Love
- Deep damp substrate - obligate burrower
- Warm and humid with cross-flow
- Gloves and eye protection for maintenance - palpal hairs
- Long tongs for feeding
- Leaving the burrow plug alone
✕ Common Mistakes
- Leaning over the open burrow - flicked palpal hairs target eyes
- Shallow dry substrate
- Digging to check on it
- Large prey - the strike exceeds the spider
