Bark Sac Spider
Clubiona corticalis
The adult bark sac spider lives beneath loose tree bark, in bark fissures, and sometimes in sheltered walls or outbuildings near woodland. It is a nocturnal wandering hunter that does not build a prey-catching web, instead rushing small insects and other arthropods from cover. During the day it rests in a flattened silk sac, which gives sac spiders their name. Its notable pale-to-brown body and strong front legs help it move quickly over bark while using venomous fangs to subdue prey.
