This morning I go out to the hive and find bee "shells". They look like bees with all the insides sucked out. Just empty shells. There is also a lot of soft brown matter and what looks like a bunch of larvae and eggs. Any idea what is going on here?

I tried to upload a picture but could not manage it so here is a link to the photo. www.speedysoftusa.com/images/bees.jpgbees.jpg
