I found this darling after work the other day. Eveningtime, autumn weather, in the parking lot. It was about 2 inches long, see photo of it in a plastic cup. Long legged, with covered wings like a beetle, but kind of soft to the touch, not crunchy like a typical beetle shell. It was trapped in a puddle, so I dried it off and made sure it was ok before I let it go into the weeds. :)

Hi Casey,
You rescued a False Bombardier Beetle in the genus
Galerita, and you can read more about this predatory Ground Beetle on BugGuide.  We are tagging this posting with the Bug Humanitarian Award.

I found this bug in my living room. It had a black body with yellow legs and the body color in a flashlight is a emerald color. I hit it really hard on the floor with a thick hard yellow pages book. And when I thought I killed it, it took off running really fast and hid behind my TV Stand table. I got this really powerful roach and beetle killer but the insect didn’t die and kept running until it slowed down 8 minutes later. Please help.

Here is a better picture.

Dear Brook,
This might be a Tiger Beetle, and in our opinion, these beautiful beetles, which you observed look like emeralds, are much more attractive alive than dead.

Hi bugman,
I’ve seen these bugs in large groups in a snake trap. They have been seen eating caterpillars, and were found with a dead mouse. We are calling them creepy beetles that seem to be very aggressive and vicious.

Dear Intern,
We have problems with the use of the term vicious to describe a predator that is capturing prey to eat.  This is a Caterpillar Hunter in the genus
Calosoma, quite possibly Calosoma semilaeve, a species we featured numerous times in 2008 when we received numerous reports from Southern California, prompting us to name it as a secondary Bug of the Month for May 2008. We believe your Caterpillar Hunter may be Calosoma semilaeve, a species posted to BugGuide under the name Callisthenes semilaevis, indicating that it is in a subgenus.  Caterpillar Hunters are very effective predators that feed primarily on Caterpillars and other insects, so they are incredibly beneficial.  We imagine they might be opportunistic feeders that take advantage of dead animals like the mouse you found.  This species seems to experience years of few sightings, and then sudden population explosions, perhaps linked to years when desert caterpillars like the Whitelined Sphinx Caterpillars are also plentiful.

Hello and thank you for responding to our resourceful intern! I have worked here at Organ Pipe Cactus National Monument (Arizona) for over 25 years and have never seen anything like this. We do get “blooms” of insects and this is certainly one. We have abundant caterpillars, as we frequently do in summer, of Hyles lineata and so they are certainly plentiful. The beetles do seem at first to be a little “creepy” in their behavior but I would not call them vicious. So it goes.The odor is a bit much, but I have become accustomed to and now rather enjoy the odor of Pinacate beetles (Eleodes).
We have some really nice photos of other insects “in bloom” – mostly beetles and bugs – and would be happy to share if you like.
Again, thank you!

Hi Charles,
We would love to receive your other insect images.  Please use the standard form when submitting them.  Great World Cup image, but sadly, we won’t post images that we cannot get permission to include online.

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.

Dear M.A.,
We agree that this sure looks like a Ground Beetle in the genus
Pherosophus, based on this image that we located online at http://jcringenbach.free.fr/website/beetles/carabidae/Pheropsophus_africanus.htm.
