Found this fellow under a moist hanging flower basket that I had set in the shade. Beautiful large black sheened beetle with two distinct blue spots. Should have measured but over an inch I’d say. Can’t find him on the web.

Caterpillar Hunter:

European Ground Beetle

Dear Michelle,
Your European Ground Beetle,
Carabus nemoralis, is quite beautiful, and we can’t quite bring ourselves to consider it an Invasive Exotic species, though we speculate it might be displacing related species that are native and that occupy the same niche on the food chain, and they might also be eating caterpillars of endangered species, but on the flip side of the coin, they may be contributing to the diets of insectivores or all phyla.

Hi, this is a picture a friend took of a bug in Nunavut, far north of Canada. I’m not sure anyone can identify it, as it seems to be sparkling with wetness of some kind.

Marsh Ground Beetle

Marsh Ground Beetle

Dear Margaret,
Initially we thought this might be a Tiger Beetle, and we knew it looked familiar, and we had a vague memory from long ago of receiving an image of a similar looking beetle
, and though it was related to the Tiger Beetles, it was actually classified differently.  Well, we eventually found this image of a Marsh Ground Beetle in the genus Elaphrus in our archives, and we believe your individual looks very similar.  This image of Elaphrus americanus from BugGuide looks very similar.  According to BugGuide, it is found:  “From the arctic treeline south to central British Columbia and east to Newfoundland. Along the pacific coast from British Columbia to southern Oregon, eastward across southern British Columbia to southwestern Alberta, south to northeastern Oregon, central Idaho and central Colorado.”

Who or What Killed the Fiery Searcher???

Who or What Killed the Fiery Searcher???

Dear Chris,
This magnificent Ground Beetle is a Caterpillar Hunter commonly called a Fiery Searcher,
Calosoma scrutator, and it is considered a beneficial insect.  Predatory Fiery Searchers help to control populations of caterpillars and other insects, and though you did not specify how this individual met its death, it appears to be Unnecessary Carnage.  One of our missions is to educate our readers about the importance of the interconnectivity of all life on our planet, and to urge our readership to learn to appreciate and tolerate the native bugs that though they may appear scary, are actually quite harmless, like this gorgeous Fiery Searcher.

Hi! My brother found this odd looking centipede in our house. Definitely, this is not a centipede because it only got 6 legs. I tried doing some research but can’t find any match. We’ll really appreciate it if you can help us identify this creature.
Thanks, WTB!

Beetle Larva

Beetle Larva

Dear Jop,
Without doing any research, we suspect this is a Beetle Larva, most likely the larva of a Ground Beetle in the family Carabidae.  Carabidae of the World has some very similar looking images of a species identified as
Carabus (Morphocarabus) karpinskii.  This most resembles larvae of the Caterpillar Hunters, a group of large predatory Ground Beetles.  We have not had any luck matching your images to online images from the Philippines.

Probably Ground Beetle Larva

Probably Ground Beetle Larva

Hi Daniel,
Wow! It’s a larva. It must be a very big beetle then when it matures because this larvae measures around 2 and a half inches.
Thanks Daniel for your response!
We appreciate it.

Subject: What’s this bug??

I find these every year in our pool filter basket (there were 5 in it this AM) West Central Ohio, May through summer.
They are about 1″ long, dark brown, almost black. Is this anything that would be coming from the lawn or be hurtful to the turf? It seems that I see more of them within a week of the Fertilizer man spraying the lawn, but they seem to be attracted to water. I don’t see them in the house, or in the lawn, just in the pool filter basket. ??? Can you tell me what this is? The photos were taken on a white paper towel for maximum contrast. I have looked on the internet, but can’t find anything exactly like this.

Big Headed Ground Beetle

Big Headed Ground Beetle

Dear Judy,
This is a Big Headed Ground Beetle in the genus Scarites, and it is a beneficial predatory species that according to BugGuide are:  “nocturnal predators on other insects.”  Perhaps they are falling in the pool filter while hunting, though we suspect you have a healthy population to be finding so many casualties.
