Asagena
Asagena is a genus of cobweb spiders (family Theridiidae) established by Carl Jakob Sundevall in 1833. It comprises nine species distributed across North America, Europe, Asia, and North Africa. Members are small spiders (2.4–5.9 mm body length) that construct webs in sheltered microhabitats including under stones, in leaf litter, under bark, and in moss. The genus was formerly classified within Steatoda.
Asagena americana
Two-spotted Cobweb Spider, Twospotted Cobweb Spider
Asagena americana, commonly known as the two-spotted cobweb spider, is a small theridiid spider native to North America. Males are notably robust with short, muscular legs and possess a stridulating organ used to produce sound during courtship. Females construct cobwebs in concealed microhabitats including under stones, in leaf litter, under bark, and in moss. The species exhibits pronounced sexual dimorphism in body form and is frequently preyed upon by mud dauber wasps.
