Large Caddisfly - Ptilostomis - female

Large Caddisfly - Ptilostomis - Female
Snowhill Road north of Cabin Branch Creek, Durham County, North Carolina, USA
May 3, 2007
Size: 24 mm
Found at a light, the same location where I have seen this species several time, and in several successive years at the same times (spring and fall). Captured and length measured: 24 mm (head to wingtips), 19 mm (body). Several photos taken to show anatomic characteristics of the family. This is believed to be a female due to the number of segments in the maxillary palpi (5, and I initially thought 4!)--see other images.

This is likely Ptilostomis ocellifera, see comments here:
