Hi WTB!
I thought you might like these pictures of tiger beetles I took at Short Hills Provincial Park. I like how one is a brilliant green and the other is a more sapphire colour. I noticed both beetles making a pose where they leaned back, almost as if to get a better view of their surroundings. Do you know if that’s a hunting behaviour or perhaps a reaction to my presence?
It was a very colourful day for bugs, as you can see — I was also able to see many Ebony Jewelwings, and they exhibited a similar range of colours. Some were a lighter aquamarine colour, and some, like the last picture provided, were more of an indigo colour.
Anyway, I love your site, and hope you enjoy these pictures even if you don’t post them. Thank you for the great service you provide :)

Six Spotted Tiger Beetle

Six Spotted Tiger Beetle

Dear Brad,
Your Tiger Beetle images are beautiful.  The green individual is a Six Spotted Tiger Beetle, and according to BugGuide, it is described as:  “Brilliant green coloration with six white spots distinctive. Occasional variation: bluish overall color, or spots missing.”  That could mean that both of your images are the same species.  Tiger Beetles are excellent hunters with good eyesight, and they are quite wary of people, so we are uncertain if the behavior you witnessed is typical hunting behavior or the result of sensing a large human nearby.  We will create a separate posting for your Ebony Jewelwing image.

Hello! My mother found this weird beetle trying to get in our back door this morning. I’ve never seen a bug like this, and I’m wondering what it is. Please help!

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.

One inch long, half inch wide beetle with black head, blue mid-body edged in red, and green back body edged in red. Underside was primarily red with gold accents. Black legs. Iridescent. Noticeable chompers.

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.
