“What is this?” asks this reader about the semi-transparent worm-like organism pictured below. “I was in my house and it was on the back of my neck. I have pets and I am disgusted.” Based on the shape and features of this creature, we would say that it is definitely an insect larva of some kind, though what species in particular we are not sure. The black tip and tapered shape of its body reminds us of a black soldier fly larvae, yet the transparent nature of its skin suggests otherwise. Based on that, we would say it is likely that it is some kind of fly larva.
