I visited your galleries this evening. You have a lot of great shots. I'll be returning for help with IDing bugs in my BA backyard.

Mark,
found an image of yours on BugGuide labelled "Tegeticula yuccasella". Yucca moths have been my main research organism for quite some time, and I revised the yucca moths, so I'll try to help with ID. Your specimen is a bogus yucca moth, a non-pollinator whose larvae develop in the main flowering stalk. It is either Prodoxus quinquepunctellus or P. decipiens; the two species mostly separated along an E-W axis, but you live in the contact zone. A final ID would require a check of the genitalia. I hope this may be of interest to you.
