In my west hive beetle trap on my week hive, I found two worms that were in a a loose dark cocoon. The worms came out as soon as I disturbed them. The were about 3/8 - 1/2 inch long and 2 millimeters wide.
I did not open this hive up today other than to check for the West Hive Beetle trap which I posted about separately. I may need to open it up to check for moths.
