Habits and Life History:
Dysderid spiders are usually found in warm habitats in rotten leaves. And they communicate by releasing chemical signals, and other spiders pick these signals.
They do not rely on webs to catch prey and hunt at night. They can be found in higher concentrations where woodlice are present. And they can jump higher when defending against attackers.
Adult female deposits the eggs on the surface contaminated with isopod secretions, egg hatches, and 1st instar larva stands up with anterior end forward and to the slides.
1st instar larva enters through the intersegment membrane of the freshly molted host, and the larva feeds on hemolymph
The adult emerges from the pupa, and the cycle repeats.
