Found hanging a few feet off the ground from a single thread of silk from the trees above. Picked up a leaf to put it on to see what it was, then moved it to nearby foliage. This is the second one I've found, and both have done the same thing, which is park under the leaf I put them on and then change into this form. sanna_heid on iNaturalist linked me to this, saying it may be a beetle larva of some kind, such as a dusky lady beetle. Any ideas?

More pictures of this specimen here, and more from the first one here.
