Ugh, one day a couple years ago we actually saw them migrating. From one side of our yard to the other! There were tons of them, inching across our driveway. Some had hatched out of their cocoons, others were dragging them with em.
I can’t even stand touching them long enough to rip them off the tree. I don’t even know why they gross me out so much. It must be how they make their home, that’s just their spit and some tree parts, right? Bleck!
