Draft: A Photographic Guide to the Female Genitalia of Orb Weavers (Araneidae)

The scape and epigynum are quite often used to differentiate between simiar species. Other characteristics used include the palps, second tibia in males, abdominal shape, coloration, pattern, etc. Someday I might add those here as well, but for now I'm going to start by gathering our epigyne/scape images. (Bugguide only covers species in the contiguous US, Alaska & Canada)
