Notched Mouth Ground Beetle Larva

Dear Stumped in Ohio,
This is one gorgeous Beetle larva.  We quickly identified it on BugGuide as a Notched Mouth Ground Beetle larva from the genus
Dicaelus.  According to BugGuide, the habitat is “Woodlands, esp. deciduous. Usually found under rocks, logs.”

I found these beetles mating when I was going out for a walk. The blueish lining on the edge of the beetle and the pinchers were very interesting. I’ve searched online for this type of beetle but I found nothing. Please help me identify this beetle.

Mating Warrior Beetles

Dear Seiya,
Despite the large mandibles, these are not Stag Beetles.  They are Ground Beetles in the genus
Pasimachus which Arthur V. Evans refers to as Warrior Beetles in his book Beetles of Eastern North America.  A similar looking individual is pictured on Ohio Birds and Biodiversity, and it is called a Blue Margined Ground Beetle, Pasimachus depressus.  This image from BugGuide is not too different from your image.  BugGuide does not provide a common name, but does provide this description:  “Large, black, elytra and pronotum often bordered with blue/violet. Elytra of male shiny, of female dull, neither have striations or punctures. Base of pronotum (next to abdomen margined). Hind tarsus long and slender.”

Six Spotted Tiger Beetle

Dear BettyLou,
This is a harmless, beneficial, predatory Tiger Beetle, most likely an unspotted Six Spotted Tiger Beetle,
Cicindela sexguttata, which is pictured on BugGuide. where you will find this comment:  “C. sexguttata generally become less spotted as one goes west, so many individuals in Iowa are likely spotless.”

A neighbor of mine posted something about this bug. None of us knows what it is and I was wondering if you knew? I tried to google it but no luck….

Virginia Metallic Tiger Beetle

Dear Penny,
We began our research on identifying this Tiger Beetle with a web search that led us to the Beetles in the Bush site, where there are images of the Florida Metallic Tiger Beetle posted, and they look so similar to the individual in your images, that we suspected they might be in the same genus, so we searched the genus 
Tetracha on BugGuide which led us to the Virginia Metallic Tiger Beetle, Tetracha virginica, which is featured in some nice BugGuide images.  According to BugGuide:  “Crepuscular or nocturnal. Hides during day under stones, rocks, etc., especially near water. Attracted to lights at night” and it is described as “Tiger beetle shape. Glossy green body and elytra, distinctive compared to Cicindela species. Legs are a contrasting tan. Elytra lack maculations. Compared to other members of this genus, no light crescent-shaped markings at apex (tip) of elytra. Note also large size–largest North American member of this genus.”  Tiger Beetles are fierce hunters that pose no threat to humans, and for that reason, we are tagging this entry as Unnecessary Carnage.  We hope you inform your neighbor that these beautiful beetles, much prized by collectors for their gorgeous metallic colors, are beneficial in the hope that future encounters to not end with a death.  As an aside, though named the Virginia Metallic Tiger Beetle, this species is actually reported as far west as Texas and Oklahoma based on BugGuide data.

Big Headed Ground Beetle

Dear Curtis,
We are pretty certain this is a Big Headed Ground Beetle,
Scarites subterraneus, but if we are wrong, it is a relative in the same genus.  You can verify our identification by comparing your image to images posted to BugGuide.  Ground Beetles are beneficial predators that pose no threat to humans.  We are post-dating your submission to go live to our site later in the month when our editorial staff is away from the office on holiday.

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!

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