Mr. Bugman,
I found the insect in the pictures on the floor of my kitchen this evening. From the research I’ve done, I am leaning towards some variety of stag beetle. Most of the descriptions I’ve found include black as a possible stag beetle color, but the only pictures I’ve found are for those with giant mandibles like the UK variants.
I’m hoping you can confirm it’s an innocent but misplaced stag beetle that wandered inside, and not some vicious, infectious pest, as my bug-a-phobic mind always assumes.

Dear Elizabeth,
Though it resembles a Stag Beetle, this is actually a Big Headed Ground Beetle,
Scarites subterraneus, or another member of the genus.  This is a beneficial, predatory species and it will not cause any problems for your home or its inhabitants.  You can find additional information on BugGuide where it states:  “adults are nocturnal predators on other insects.”

Good Morning,
I’ve just returned from Colombia, South America and I’ve managed to identify everything except these remaining photos. I hope you can assist. They’re tricky, that’s for sure!

Tiger Beetle

Hi again Cokey,
Your Tiger Beetle looks very similar to this FlickR image from Costa Rica that is identified as
Pseudoxycheila tarsalis.  According to Carabidae of the World, it is found in “Colombia, Costa Rica, Panama.”

Wondering what kind of bug this is. We are in Massachusetts, north of Boston. It is February 10, ~3:30pm, ~35 degrees F, cloudy, very light snow falling intermittently.

Dear Kim,
There is not enough detail to be certain, but we believe this is a Ground Beetle in the family Carabidae.

I live in northern Congo and regularly come across interesting insects, some of which are probably little known or unknown to science.
I try to identify many of the arthropods I see here via iNaturalist, but many can use a lot of extra help – always appreciated!

Unknown Ground Beetle

Craspedophorus Ground Beetle

Dear Naftali,
We agree that this is a Ground Beetle in the family Carabidae, but at this time we are unable to provide you with a more specific name.  Perhaps one of our readers will provide a comment.

Via iNaturalist a good bet seems Craspedophorus sp.
There are many spp. though…

According to a published paper we found, that genus is from Australia and Asia, but in Google Books Taxonomy, Phylogeny, and Zoogeography of Beetles and Ants online, it indicates:  “The carabid genus Craspedophorus, with over a hunderd species distributed through tropical Africa, Madagascar, Asia, and Australia is notable partly because of its usual dorsal color pattern, which consists of four yellow or orange spots on a blackish elytral background.  The spots are normally at or near the lateral margins of the elytra, two on each elytron, and when they are extensive, the dark background has even been described as forming a cross.”  Colnect indicates one species is pictured on a stamp from Portuguese Guinea.  The first species pictured on Carabidae of the World , Craspedophorus abnormis, is reported from “Democratic Republic of the Congo, Tanzania, Zimbabwe, Zambia,” but alas, there is no image.  We believe you have discovered the correct genus.

No way to undercover (or name?) the species? I am just near the trinational border Cameroon-Congo-CAR…on the Congo side.
