Oil Beetle

Dear Charlee,
We just posted another image from Michigan of an Oil Beetle.  According to BugGuide:  “the common name refers to the habit of exuding yellowish oily liquid from the joints when molested” which your image illustrates.

My cat found this one.  If you mess with it, it plays possum. The pictures don’t do the iridescence justice- it’s a subtle blue.

Oil Beetle

Dear Curious in MI,
This is a Blister Beetle in the genus
Meloe, commonly called an Oil Beetle.  According to BugGuide:  “the common name refers to the habit of exuding yellowish oily liquid from the joints when molested” but we have always speculated that Oil Beetle might be a reference to the iridescence you noticed, because it does look like a thin layer of oil on the surface of water.

Found in sandy soil about 30 yards from a medium sized lake. A white pine forest surrounds this lake with the occasional clearing. I figure this is a queen of some sort, I’ve been looking around myself for a while. I can’t find a match.

Oil Beetle

Dear Tyler,
We have received several requests in the past few days to identify Oil Beetles in the genus
Meloe, but your image is by far the best, hence it is the only one we are posting to our site.

Spotted Blister Beetle

Dear Shay,
We are confident we have correctly identified your Spotted Blister Beetle,
Epicauta maculata, thanks to this BugGuide image.  Though BugGuide does not report any sightings from Idaho, there are sightings from nearby Montana and Wyoming.  Blister Beetles should be handled with extreme caution, or even better, not handled, because contact with the cantharidin that many species secrete can cause blistering in human skin.
