Idiothele mira

🔤 Taxonomy

Idiothele mira is the currently accepted scientific name used for this care guide. In hobby listings, use the Latin name carefully because common names are informal and may be reused for related Old World tarantulas.

Names used in the hobby:

blue-foot baboon
trapdoor baboon tarantula
Blaufuß-Baboon

📌 Description

Idiothele mira is a small Old World fossorial tarantula. It is associated with dry to seasonally moist ground retreats and silk-lined burrows. Adults are usually about 3-4 cm body length and 8-10 cm legspan. Females often live 8-12 years, while mature males live much shorter lives.

The care priority is the trapdoor-style retreat. A display setup should let the keeper observe the entrance and body condition without exposing the spider. If the enclosure is too open, too wet, or disturbed too often, the animal may seal itself away or abandon the entrance rather than behave naturally.

Before buying one, prepare a small, stable, well secured enclosure. With this species, repeated moving and digging into the burrow are bigger problems than rarely seeing the spider itself.

Provide a warm area, drier surface, slightly moister lower layer, and constant water. Record feeding, molts, and changes at the burrow entrance; with a hidden species, those small observations matter.

☠️ Venom

Respect the bite risk. Old World tarantulas can be fast, defensive, and capable of painful bites that may produce swelling, cramps, nausea, dizziness, or stronger individual reactions. Maintenance should be planned so hands never need to share space with the spider.

🌍 Distribution

Idiothele mira is native to South Africa. In captivity this means a protected burrow, dry to moderate conditions, clean water, and good ventilation. Do not keep the entire enclosure constantly damp; the spider should be able to choose between drier and lightly moist areas.

In captivity, that background points to:

secure retreats and visual cover
a measured thermal gradient instead of one uniform temperature
humidity that matches the species without stale wet air
clean water and predictable hygiene
enough usable structure for normal movement

Use the range as context, not as a weather script. Wild tarantulas hide in buffered microclimates, so the enclosure should offer choices rather than constant spraying or one fixed condition.

⚖️ Legal status

As checked against current CITES, Species+ and EU wildlife-trade references on 31 May 2026, no current CITES listing or species-specific EU Annex listing was found for Idiothele mira. The species is outside the scope of the Bern Convention because it is not native to Europe. National and local rules on import, ownership, sale, breeding, transport, animal welfare, and proof of legal origin may still apply.

Good records start before the animal comes home. Save breeder or seller details, molt and sexing notes, locality claims, transfer documents, and clear photos of the animal.

🤌 Husbandry

For an adult, plan around 20 x 20 x 20 cm with enough deep, firm substrate for a burrow. Slings should start in smaller containers where prey is easy to find and moisture is easier to control. Keep this species singly.

Use a smaller, stable enclosure than you would for a large baboon spider, but do not make it shallow. A firm starter burrow against cork, a slight slope, and leaf litter or moss fragments near the entrance help the spider build a hinged or covered doorway. Feed near the entrance and remove missed prey promptly, because a small hidden spider is easy to injure with roaming insects.

Make routine work predictable. Secure the lid and vents, remove collapse risks, and plan feeding, watering, and cleaning so the enclosure is never held open longer than necessary.

💡 Lighting

Tarantulas do not need specialist lighting; a regular room day-night rhythm is enough. Avoid direct lamps that overheat or dry the enclosure too aggressively. Quarantine new arrivals in a simple secure setup before moving them into a display enclosure.

🌡 Heating and temperature

Practical temperature targets: 23-27 °C by day, with a slight night drop. Measure with reliable instruments. Stable warmth is useful, but overheating and stagnant hot air are more dangerous than a mild night drop. Change one variable at a time and avoid correcting every minor behavior with extra heat or repeated feeding attempts.

💧 Humidity and water

Keep the surface mostly dry to moderate, with the lower burrow zone lightly moist. A small dish of clean water should always be available. Moisture should stay local; a wet, closed container quickly leads to mold around the entrance.

🌿 Enclosure and decoration

Build habitat first and display second: secure retreats, water, web or burrow anchors, safe movement routes, and enough cover for normal behaviour. Keep decoration functional and leave enough access for safe cleaning and observation.

The substrate should be firm enough for a neat burrow and dry enough on top that the door does not turn moldy. Keep one lower corner lightly moist and leave the opposite side drier. A water dish can be very small but should still be present; dehydration is harder to spot in a species that spends most of its time behind a sealed entrance.

🪳 Feeding

Suitable diet: small crickets, roach nymphs, small locusts, and other prey sized to the spider. Remove uneaten prey and food remains. Feed according to body condition, not only appetite, and avoid leaving live prey during premolt. A fasting spider is not automatically in trouble, but refusal with weight loss, dehydration, or weakness needs a husbandry check.

🥚 Breeding

Do not breed just because a pair is available. Confirm identity, condition both animals, prepare offspring housing, and avoid hybrids or uncertain locality crosses. For defensive Old World species, pairing and separation should be planned before the animals are introduced.

🩺 Common problems

The most common problems are a collapsed burrow, an overly wet entrance, mold, dehydration, and unnoticed leftover prey. If the spider stops repairing the entrance, looks shrunken, or ignores food for a long time, first check water, lower-layer moisture, ventilation, and burrow stability.

Do not open the trapdoor just to see the spider. Long hidden periods are normal, especially before molt. Intervention is justified if the entrance collapses, mold persists, mites appear, the abdomen is severely shrunken, or there is visible injury.

For serious injury, leaking hemolymph, or a difficult molt, seek an exotic-veterinary professional when possible. A short log of feeding, molts, and changes around the entrance is much more useful than frequent digging.

📌 Conclusion

Idiothele mira is a species for patient observation. Success comes from a stable burrow, moderate local moisture, and minimal disturbance, not from frequently opening the enclosure.

Keep provenance documents and short notes on feeding, molts, water, and the state of the entrance. With this hidden species, those small records show whether care is going well.
