We’ve got several of these weird little things hanging from odd places on the outside of our house. This one is hanging low near the foundation but most of them are hanging higher in window frames. It’s about 3” long.
Paul looked it up online. This is a bagworm, actually a caterpillar. I think that a moth is going to emerge from this weird little structure. Bagworms are the only species that uses plant debris to build their sacks. So those are leaves from our Live Oak trees.
It’s a little creepy. But I’m glad it’s just moth. That doesn’t seem too threatening.
Here’s more info from Texas A&M.
