I can't say that I especially want to say anything more about small hive beetles. They don't look like an organism that ought to be able to do a lot of damage. Rather small, hard-bodied little critters that shouldn't bother anything. But then, it's not the adults that are the problem except for the eggs that they lay. And they lay a lot of eggs. It's possible to run across larvae in the thousands. All of that is just to say it seems proper to put up a couple of pictures that show the beetle itself. The picture in the previous post only shows the larvae. The first image gives an indication of size. So small yet so nasty (a consistent theme in bee pests apparently).   Note the disc-shaped antennae--they are very obvious when you run across an adult hive beetle.
