Owww! That was my antenna!

On the funny shift today at work and as I was leaving to go back at 4 o'clock I opened the door to find a little visitor.
The first shot I tried though, I managed to slam into tap its head with the lens and so it shrunk back into its shell. This shot, #2, was as it was just sticking its antenna back out again, probably in the hope that I'd already gone.
