About
The Highland Birdeater ("Theraphosinae sp. Highland Blue", also traded as sp. "Cuzco") - an unknown genus AND species from the Peruvian Andes around Cuzco, listed beside the Antikuna Herradura form as a future "big one" by the vendor. Blue-tinged montane stock with moderate dry-side care; every parameter here is the trade baseline for a species literally nobody has identified yet. £35 CB slings for Andean-form collectors.

Is my Highland Birdeater Tarantula dying or moulting?
Pre-moult signs to look for
Refusing food for weeks is normal before a moult - a healthy Highland Birdeater 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 Highland Birdeater 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 27-54 days for spiderlings, every 65-108 days for juveniles, and every 150-240 days for sub-adults, with adult females moulting around every 10.7 months (up to 15.3 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 Highland Birdeater Tarantula need?
🪞 Moulting
Signs: refuses food, abdomen darkens, becomes sluggish. Do not disturb; keep water available; wait for black hard fangs before feeding. Adult intervals apply to mature FEMALES - a mature male never moults again.
🧹 Cleaning
Daily: check the water dish. Weekly: remove boluses and spot-clean.
✋ Handling
Suitability-rated 2/5 by the vendor - handle rarely and low.
