Does anyone know what this is? There was some kind of insect inside when I initially saw it crawling on the ground but it quickly withdrew and now the end is just moving slightly (as seen in the video here ). #insect #pine #entomology #entomologist
That is a bag worm caterpillar. It is a type of moth caterpillar that builds a protective case out of leaves or pine needles. They are cool bugs, but they can be destructive if there are a lot of them.
