Tegenaria domestica
Barn Funnel Weaver, Domestic House Spider
Tegenaria domestica is a funnel-web spider in the family Agelenidae, native to Europe but now distributed nearly worldwide through human introduction. It is one of the smaller species in its genus, with females averaging 7.5–11.5 mm and males 6–9 mm in body length. The species is notable for building characteristic funnel-shaped webs and for recently documented colonial behavior in a unique cave environment in Greece/Albania, where thousands of individuals cooperatively maintained a communal web exceeding 100 square meters.
