Bagworms have been munching on the needles for weeks and we wonder how it all happened.
Well, they are at work right now so go outside and take inventory of your evergreens because that's what the bagworm likes the most.
Bagworms can easily be recognized by their cocoonlike cases, which are carried about by the larvae as they feed.
Each larva constructs its bag of silk and bits of leaves and twigs cut from the host plant, so a bagworm 's appearance will vary from plant to plant.
Although bagworms can be found feeding on black locust.
My husband noticed some bagworm cases attached high up on the side of our house.
