I remember reading somewhere that psalmopeous, tapinauchenius and avicularia like to use leaves to make silk retreats in the wild. I also read that heteroscodra and stromatopelma like to live in the crowns of palm trees. I found some great plastic palm fronds and intend to use them to make hides for my psalmos, tapins, heteroscodra, stromatopelma and avics. However, i also read that poecilotheria, lampropelma and cyriopagopus like to live in the hollows of trees. Does this mean that they wouldn't make their own silken retreats from plastic palm fronds and that i must find a length of bamboo or corkbark? I also have a p. murinus, p. lugardi and p. chordatus that I plan on setting up semi-arboreal. Would the plastic palm frond idea work or would a bamboo or corkbark tube work better?
