 The next insect on the list is the pine webworm and the pine webworm feeds and makes its nest inside the branches of the pine. It leaves frass and webbing where it puts its nest together and they feed on the needles so you can see where all the needles have been fed on and all the tops of them are gone and you can see all the frass and the webbing inside the pine branch here. It's very distinguishable. It's very easy to see the damage that's caused by the pine webworm. Again, they just make their nest and it's all this frass and webbing. Everything stays within this pocket where they're feeding and they just feed within this area and they don't leave. It's a very nondescript brown caterpillar, the larvae, that you might also see if you get this insect on your test.
