Caterpillar Hunter

Black Caterpillar Hunter

Dear Tayne,
This beautiful beetle is a beneficial Black Caterpillar Hunter,
Calosoma sayi.  You can compare your image to images posted to BugGuide.  According to BugGuide, it can be recognized by being:  “Large, black, with prominent gold or red punctures and blue or green margins of elytra. (These are not prominent on cursory inspection–the beetle appears all black.) Resembles C. calidum but larger (25-28 mm vs. 16-27 mm) and more southern in distribution. Quoting from Ciegler (2000).”  The red punctures are visible in your image despite the lack of critical focus and clarity.

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
