Biologist's nightmare

In November I opened up a box of my data sheets for the first time since I packed them up in Nyota and saw a teeny little beetle run and hide between the sheets! I searched between every sheet, paperclip, and postit to find and squish two beetles. Now almost 8 weeks later, I found a similar looking beetle (or is it larger?) hanging out on the edge of my mug, probably in search of water. I have encased this one in scotch tape.

Ack! I hope there aren't any more. We don't need any more invasive species.
