Bennett's Laceweaver
Callobius bennettiAlso known as Hacklemesh Weaver, Night Spider, Tangled Nest Spider
Bennett's laceweavers spend daylight hours concealed beneath rotting logs, flat rocks, and loose bark within temperate North American woodlands. At night, they construct irregular tangled retreats fringed with specialized cribellate silk that snags passing prey like Velcro without relying on sticky glue droplets. Females display extensive maternal care, guarding their silken egg sacs and ultimately offering their own bodies as nourishment for their newly hatched spiderlings.
