What is that?

That’s what we wondered at the Doeskin Ranch on November 24th after Eve spotted this strange thing and waited for me to catch up from my picture-taking so she could point it out. I’d read about insects that cover themselves with objects to act as camouflage, and that’s what appeared to have happened here. To learn the specifics, I turned to local expert Val Bugh, who identified this as “a bagworm moth case (Psychidae). Our big species here is Oiketicus abbotii (if I’m correct in estimating your example is about 2 inches long [she was correct] — the small species are less than half as big). This bag is empty and the exuviae is sticking out the bottom, indicating a male eclosed and flew off. The females never leave their sac.”
