Rove beetles, like one of last week’s subjects, the silverfish, tend to be very active, but unlike the latter, rove beetles aren’t reactive to or particularly concerned with people. I managed a couple shots of this fairly large specimen, but their reliable hyperactivity is evident in the lack of sharpness of the photo’s focus. I tried to spruce that up in post-processing. (Notice the messy and characteristically-shortened elytra, a.k.a. wing covers.)
Another thing about rove beetles, at least the ones I am familiar with, is they tend to have a bit of a nasty look to them: an angry glare or unkind sneer. Basically a Monday beetle.
