I was cutting firewood yesterday and ran across a weevil on that was resting in a cut in the wood. Since it had some interesting colors I collected it in a jar to photograph later. When I captured the creature I wondered if I had killed it.
It just seemed to lie there motionless. After half a minute or so it came back to life and started to move around again. When I touched it the beetle would go motionless again, then when it was not bothered for a while it would move around.
I have seen this before in another weevil. I have heard that mourning cloak butterflies do this as well.
Here it is crawling on my arm.
