Woodlouse Spider

Natural Habitat

Under rocks, logs, leaf litter, and occasionally in dark, damp areas of homes like basements.

Diet & Feeding

Strictly insectivorous; primarily preys on woodlice (pill bugs/roly-polies) using large chelicerae to pierce their shells.

Behavior Patterns

Nocturnal hunters that do not spin webs for catching prey, but instead use silk to create retreat sacs for resting and molting.

Risks & Benefits

Generally harmless to humans though they can bite if handled; the bite may cause localized itchiness. Beneficial to ecosystems by controlling woodlouse populations.
