Had one on my shoulder last week. Thought it was a wolf spider at first. Hid it's legs tucked up just like this and buzzed hard when I tried to pick it up.
Edit: looks like it's an Eastern Eyed Click Beetle
I used to find these with my cousin all the time in central Illinois and 40 years ago (ugh, how is that possible?)... Haven't seen one in a very long time though.
