Steatoda castanea

(Clerck, 1757)

Steatoda castanea is a cobweb spider in the Theridiidae, closely related to black widows and other Steatoda . It is native to the Palearctic region, with distribution records from Europe through Russia, the Caucasus, Iran, Central Asia, and China. The species has been introduced to North America, including Canada. As a member of the cobweb weaver family, it constructs irregular tangled webs and shares the general and habits typical of the Steatoda, though specific behavioral and ecological details for this species remain poorly documented in available literature.

More Details

Taxonomic Note

Steatoda castanea was originally described as Araneus castanea by Clerck in 1757. It is one of the earlier described in the Steatoda, which now contains numerous species globally. The specific epithet 'castanea' (Latin for chestnut) likely refers to coloration, though original description details are not provided in available sources.

Data Limitations

Available sources provide minimal -specific information for S. castanea beyond taxonomic classification and distribution. Most detailed ecological and behavioral information found in sources pertains to congeneric species such as S. triangulosa, S. grossa, S. nobilis, and S. bipunctata. Direct application of these details to S. castanea without verification would constitute unsupported inference.
