Coras medicinalis
Medicinal Funnel Weaver
Coras medicinalis is a funnel-weaving spider in the family Agelenidae, native to eastern North America. The species was first described in 1821 and has undergone extensive taxonomic revision, with its current placement in Coras established by Eugene Simon in 1898. It constructs distinctive funnel-shaped webs with multiple retreats, often in human-associated structures as well as natural forest habitats. The species acquired its name from historical medicinal use of its webs in fever treatments during the 1800s.
