Caterpillar nest with webbing on Canyon Lupine

This is a nest with webbing on a new flower stalk of Canyon Lupine aka Broadleaf Lupine (Lupinus latifolius, Fabaceae) in the woods a couple of days ago. I'm sure it's a caterpillar nest -- I saw it move around in there! I already have my two photos for the Web Wednesday group, but Happy Web Webnesday anyway! (San Marcos Pass, 12 May 2025)
