Woodlouse hunter spider

Often found beneath logs, stones, and debris outdoors; also enters damp basements and homes.

Feeds mainly on woodlice (pill bugs and sowbugs), piercing their hard outer shells with its large fangs.

Nocturnal hunter that hides in a silken retreat by day; females guard their eggs and young. The pictured spider’s rounded abdomen may be enlarged after feeding or egg production.

Generally harmless and useful for controlling woodlice. It may bite if trapped or handled, causing localized pain and redness.
