Hi Joe,
This is a Caterpillar Hunter known as a Fiery Searcher, and both adults and larvae are important predators that control the numbers of caterpillars.
  We received an account earlier this year of large numbers of Fiery Searchers in Missouri.

Hi!
I’ve found this beetle roaming near the house at night, when held in a napkin it squirted a yellowish substance making a strange sound -almost like a high pitched or a whistle sound-
After a little bit of searching I’m almost certain that it’s from the Pherosophus family.
Can you give me a more accurate Identification of the specimen?
Thank you.

I had this bug sitting on my deck for hours this weekend. Can you identify it? Date was 5/18/14 in the Chicago area.
The colors were beautiful but I’ve never seen anything like it before. It was approx. 2.5″-3″ long.

These were dashing across the driveway this afternoon. I’d never seen them before so I grabbed a few….deciding that of they were something good I’d deliver them back. And if they were some invasive non-native i’d not let them live. Turns out they’re ground beetles of some sort, though what variety i couldn’t discover. And purportedly beneficial, so they all went back to the driveway. Apparantly nocturnal (?is this variety??) If so, that’d explain why i’ve never seen them before. So, if they are nocturnal, why be bright bodied? (undersides are iridescent) There’s gotta be a reason why they’re so bright and i think THAT reason is what i observed today! …. mating! our driveway is mostly creek gravel (orangish brown) with areas of limestone rock, which is white. Most of these were running up and down and across the white part of the driveway. i figure it is som

Dear Eight Pond Farm,
This is the second report we have gotten today of large numbers of Caterpillar Hunters.  The other was from Virginia.  Your Caterpillar Hunters are Fiery Searchers,
Calosoma scrutator.  They are indeed beneficial predators.

i shot a video of them all skittling about in the bucket.   wanna see it?
btw…  today, there were a few crossing the driveway, but yesterday was THE biggie!

Today I came to work in Chantilly, Virginia and our building is inundated with these beetles. At first glance I thought that they are Japanese Beetles, but something about the shape of the body tells me I’m wrong. I’ve searched several of the insect identification guides but I cannot find any photos that match this beetle.
I’d like to find out what this beetle is, in hopes of understanding why there were none yesterday and there are hundreds of them today.

Caterpillar Hunter

Caterpillar Hunter

Hi Ed,
Your beetles are Caterpillar Hunters in the genus
Calosoma. The beetle in one image seems considerably darker than the beetle in the other image, so we are wondering if they are all metallic green with red or gold borders.  We believe the discrepancy in coloration is due to camera exposure and lighting.  We also believe your beetles are most likely Fiery Searchers, Calosoma scrutator, and you may compare your images to the images on BugGuide.  Perhaps populations are peaking this year because there is a significantly larger proportion of prey, namely caterpillars and other insects.

Thank you for the quick response.  I did some searching later and you confirmed my suspicion about Calosoma Scrutator.  Truly a beautiful beetle.
