Woodlouse Spiders
The Woodlouse Spider is a specialist predator of woodlice (pillbugs and sowbugs). Its large, forward-projecting fangs are specifically adapted to penetrate the hard exoskeletons of its armored prey. Originally from the Mediterranean, it is now found throughout much of North America. It is often found in damp areas where woodlice are abundant.
