Tiny Beetles

Here are some tiny rove beetles I found the other day that push the limits of my current macro lens. In the first three pictures you can kind of see how the wings are folded up under the elytra (the shell-like covering of the wings of beetles, which rove beetles have considerably less of than most other beetles). In the last two pictures the wings are completely unfolded. I know the wings are pretty thin, but it is still impressive to me that they can just fold up their wings and put them away.
