Bagworms are a real problem. We made a major assault on them last year by picking them off of everything we could reach, tying them in plastic bags and throwing them into the trash. We have fewer bagworms this year, but we still get a few hanging around. This bagworm was very active in its leaf bag dangling from a cottonwood. I photographed its ballet-like performance before I mercilessly disposed of it.
