Larvae found in basement
I don’t know what kind of larvae this is but I never saw one quite so big. He is about 4 inches long and about ? inch thick. I live in South Central Pennsylvania USA. I am near water if that helps. This guy was crawling along my basement floor and I thought maybe you would know what he turns into or what he is? Thanks,
You have discovered a Hellgrammite, the larval form of a Dobsonfly.
