About
The Costa Rican Bluefront - a chocolate-brown Aphonopelma with striking steel-blue chelicerae and front legs, from Costa Rican dry forest. Classic New World thrift: docile, reclusive, given to sealing its burrow and fasting for weeks on end for no visible reason. Slow-growing even by Aphonopelma standards, with females among the longest-lived spiders in the hobby at 20-30 years. A patient, undemanding species that rewards keepers who like their tarantulas calm and their care schedules relaxed.

Care Guide
Aphonopelma crinirufum
Costa Rican Bluefront - a complete husbandry sheet. Use as a starting point and adjust to your individual specimen.
What size enclosure does a Costa Rican Bluefront Tarantula need?
Adults
30 × 25 cm (12 × 10 in) for a mature adult, with 10+ cm of substrate for burrowing.
Slings & Juveniles
Small deli cups with 5+ cm of substrate and a starter burrow.

What temperature and humidity does a Costa Rican Bluefront Tarantula need?
Heating
The Costa Rican Bluefronts is comfortable at 21-28 °C. Most UK homes manage for much of the year; warm the room rather than the enclosure in winter.
Humidity
65-75 %: dry-side substrate with a full water dish suits dry-forest stock perfectly.
Ventilation
Cross-ventilation is essential - side-vented enclosures, never stagnant.
What substrate is best for a Costa Rican Bluefront Tarantula?
Recommended Mixes
Depth
10-12 cm
Notes
Deep (10 cm+), packed firm - this species builds real burrows. Keep dry to barely moist.
How do you set up a Costa Rican Bluefront Tarantula enclosure?
Décor
The Hide
A starter burrow under a cork slab or half-log - most excavate a deep retreat and spend weeks at a time sealed in.
Water
Always provide a shallow fresh water dish - especially important during long fasts.
Lighting
No special lighting needed. Ambient room light is enough.
How often should you feed a Costa Rican Bluefront Tarantula?
Good Feeders
Long refusal worrying you? Separate premoult fasting from genuine problems with our "Is my T okay?" checker.
Is my Costa Rican Bluefront Tarantula dying or moulting?
Pre-moult signs to look for
Refusing food for weeks is normal before a moult - a healthy Costa Rican Bluefront Tarantula fasting is almost never an emergency in itself. Watch for slowing down and spending more time in the hide, 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 Costa Rican Bluefront 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 28-56 days for spiderlings, every 70-115 days for juveniles, and every 160-250 days for sub-adults, with adult females moulting around every 11 months (up to 15.7 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.

What ongoing care does a Costa Rican Bluefront Tarantula need?
🪞 Moulting
Almost always moults deep in the burrow, often sealed in. Do not dig to check. Keep water available, keep prey out, and wait until it reopens and the fangs are black before feeding again. Adult intervals apply to mature FEMALES - a mature male never moults again.
🧹 Cleaning
Daily: check the water dish. Weekly: remove boluses from around the burrow mouth. Full deep clean rarely.
✋ Handling
Docile and slow - a tolerant species, though long fasts make it occasionally defensive of its burrow. Handle rarely and low.
What are the most common mistakes when keeping Costa Rican Bluefront Tarantulas?
✓ What They Love
- Fresh water dish at all times
- Deep substrate for its burrowing habits
- Stable room temperature
- Accepting long fasts as normal behaviour
- Cross-ventilation
✕ Common Mistakes
- Worrying when it seals the burrow and fasts - that is the species
- Digging it up to check on it
- Soaking-wet substrate
- Heat mat underneath the enclosure
