I have several of these around my office in Hebron, KY, which is just a few miles away from the Cincinnati Airport. They’re kind of like June Bugs, but I don’t think they are. Would you please let me know what these are? Thank you!

Six Spotted Tiger Beetle

Dear Andy,
Though your image is quite blurry, it definitely depicts a gorgeous, beneficial, predatory Six Spotted Tiger Beetle.

Hi
is this a violet ground beetle? I found lots of them on my garden now the snow has cleared here in Quebec, Canada and I read that they eat slugs so I’m very excited. However I just wanted to check it is not some other type of beetle which is going to eat my plants?
Many thanks,

European Ground Beetle

Dear Anne,
We are curious where you discovered that this beetle is called a Violet Ground Beetle because that is not a common name used on BugGuide where we believe we have correctly identified this as a European Ground Beetle,
Carabus nemoralis, and according to BugGuide its range is:  “n. US & Canada, absent from Great Plains (BG data)  native to Europe, adventive in NA (in the east: NF-MN-ne.VA; in the west: BC-CA to AB-UT; isolated in the Saskatoon area, SK).”  According to Encyclopedia of Life:  “This species, in the subgenus Archicarabus, is a European introduction. Black or dark piceous, upper surface more or less cupreous or greenish bronze, sides of prothorax, and often elytra, usually violaceous. Elytron with three rows of foveae and on each interval with suggestion of five ridges, so irregular and confluent as to give a scaly appearance. Length 21 to 26 mm.”  According to Ground Beetles of Ireland:  “A very eurytopic species, clearly favoured by human activities and widespread in gardens, parks, pastureland and woods in lowland areas.”  According to thewcg.org.uk:  “Adults spend the day under loose bark or among deep plant litter, emerging at night to forage over a wide area, usually on grass or among litter but they also ascend mossy tree trunks. Prey includes slugs and snails, woodlice, millipedes and centipedes. Adults are active from early spring, breed in the summer, and persist into the autumn. ”  We are still curious where you found the common name Violet Ground Beetle because we have not found it used in relation to this species.

Thanks so much – the violet ground beetle is just my ignorance looking at pictures on the web and thinking I saw something that was the same. Thanks for your expert guidance. Brilliant service. I hope to use you again.
Many thanks,
Anne

Hello, I found this little guy in our 5 year old native wildflower garden in Stevens Point, WI on 4/26/17. He caught my eye with his bright blue outline, is this a Snail Eating Beetle? Thanks!

Dear Ben,
Your Ground Beetle is actually one of the Caterpillar Hunters in the genus

Hello! I believe this to be a type of assassin bug but i’m hoping to confirm. It is the season of April, and found on the 22nd day.

False Bombardier Beetle

Dear Kevin,
This is not an Assassin Bug, nor any other true bug for that matter.  This is a False Bombardier Beetle, and according to BugGuide:  “Caution: These beetles have chemical defenses.”  In our opinion, the chemical defenses are more of an annoyance to humans than they are a threat.

I found this bug or beetle crawling in my bed. I first heard it, as I must have laid on it, and it started making a humming type noise which woke me. It was then it was on my arm crawling. I whisked it off onto my sheet and took snapshot. Then took it outside.
I want to see if you may identify it for me?

Black Caterpillar Hunter

Dear Not Important,
This is a Black Caterpillar Hunter,
Calosoma sayi, and though they are not dangerous to humans, they do have powerful mandibles that could nip someone who tries to handle one.  According to BugGuide:  “Predatory on other insects, especially caterpillars.”
