Under-bark Jumping Spiders - Family Salticidae 

This page contains pictures and information about Jumping Spiders live under bark that we found in the Brisbane area, Queensland, Australia.
Large tree trunk with loose bark provides good living environment and shelter for small insects. It is the place for flying insects to have a short rest too. This becomes the good hunting ground for Huntsman and Jumping Spiders. We found a number of jumping spiders that are specially adapted to hunt on tree trunk with loose bark. They are brown camouflaged colours with thin and flat body suitable for fast moving under lose bark and crack. They include genus Holoplatys, Arasia and Astia.
