Liphistius makes the trip lines, but all of the mygalomorph traps I know of just rely on vibrations.I don't own one and never have but I suggest just throwing the food in there. If I'm not mistaken, they have trip lines that tell them if something edible is crawling around on the surface.
Good luck with feeding and tell us how it goes
I would say no, but I'm not entirely sure. If you could, can you disturb him for a bit, take him out, and snap some pictures.This is probably a dumb question, but do male trapdoors have hooks and if so, how dominant are they? My L. malayanus was viewable last night and it seemed like he had bulbs on his palps, but it was hard to get a good view. I could see his legs pretty well and I couldn't see any hooks. Do I have a boy?
He looks to be mature...he's probably out wanting to wander and look for females...he's not too big...maybe 3 inches...and that's mostly legs
