Natural Habitat

Found in outbuildings, around window frames, under logs, and in crevices of walls or bark.

Diet & Feeding

Carnivorous; hunts various small insects and other invertebrates that become entangled in its lace-like web.

Behavior Patterns

Nocturnal hunters that construct distinctive funnel-shaped webs of woolly, 'cribellate' silk. Notable for matrimonial cannibalism where spiders may consume their mother (matriphagy).

Risks & Benefits

Benefits the ecosystem by controlling pest insect populations; while they can bite if mishandled, their venom is not considered medically significant to humans.
