True Spiders / Huntsmans

MOQ 20 head

Partners Only

2.5 – 3.5 cm body; dark, heavily armoured tergite plates.

Mesothele mygalomorph with mild, medically insignificant venom; large fangs deliver a mechanically sharp but harmless bite. Reclusive — bites are very rare.

Endemic to Thailand (recorded from western/northern hill forest, e.g. Tak). Builds a trapdoor burrow in firm, shaded earth banks with silk signal lines radiating from the door. 200 – 900 m.

Ground arthropods — ants, beetles, crickets and roaches — ambushed at the burrow entrance when they trip the silk signal lines.

23 – 27 °C ambient — 21 °C cool end (slightly cooler hill species)

75 – 90 %. Keep the deep substrate consistently moist; maintain stable burrow humidity.

None required (nocturnal / fossorial).

Crickets and roaches near the trapdoor. Adults every 7 – 10 days; slings every 4 – 5 days.

Fossorial — 8 – 12 cm of compactable moist substrate against a sloped face for the trapdoor; min 15 × 15 cm. Leave undisturbed once the burrow is established.

Very shy and secretive; retreats instantly into the burrow. Not for handling — a display species only.
