Hi all, I was dissecting Barn Owl Pellets a year ago for a friend who was doing a study on Barn Owls from 6 different locations, she asked me if I would undertake the job of dissecting them, so, I'm sitting in my shed teasing one apart when I found a grub/larva, 13mm long, creamy white with a brown head, which had an inverted V on it's frons, I also found a pupa still wriggling if touched in a case similar to caddis fly but glued together with the fur/hair from the pellet, I found more after that and thought maybe I could rear one in a container with pellets in to find out what it was, I did this and from the pupa came this moth, it took me several days trolling through books and on line till I found it, The Skin Moth Monopsis laevigella UK Moths No227 I love a challenge.

So did the moth lay its eggs in the barn owl while it was still alive? Like moths do in the fur of orangutans?

Hi NellyDee, No it doesn't lay it's eggs in the actual barn owl it lays them in the barn owl's Pellets, which are regurgitated bones and fur that the barn owl cannot digest, so when the eggs hatch into larvae they eat the hair and fur of the animals that the barn owl has eaten, they live in the pellet until they pupate after going through instar stages, when it hatches from the egg it's known as the 1st instar and when it has eaten enough and grown too big for its cuticle (body) it has to shed its skin (molt) this is known as the 2nd instar, it may eat it's old cuticle recycling the protein and other nutrients back into it's body, Ain't Nature Grand!
