Curved #arrow worms?
I've seen 2 or 3 of these in this session. Has anyone else seen curved #arrow worms? Is it a known behavior? Is there always something attached at the curve?
I've seen a lot of curved ones. I get the impression they are quite flat and they flex in the up/down dimension but not so much in the side to side dimension, if you see what I mean. Sometimes you will see one side-on and they tend to be the curved ones.
I think the white blob in the image you posted is some "snow" that just happened to be in front of the arrow worm.
