I’ve been interested in bugs for as long as I can remember.
I love observing and learning about them, my favorite is the Hummingbird Moth.
I own an IPad Mini so these pictures aren’t as clear as i’d like them to be, but i hope it’s clear enough for the identification of the insect.

Dear BzyBee,
Though it does not resemble a typical member of the Beetle order Coleoptera, this Brown and Gold Rove Beetle is a beetle nonetheless.

Hello! The other day, we had a visitor to the optical practice where I work. I’m 90% sure this is Ontholestes murinus; I was sure it was a rove beetle at the time and although I wasn’t expecting to get such a precise ID, I stumbled upon O. murinus when researching it later. I can’t tell you anything about where it came from, only that there are a couple of green areas around the corner from the practice and that when I chucked it outside, it took off before it even hit the pavement. It was very fast and had large mandibles, and it did raise his tail a few times as a Devil’s Coach Horse would. What do you think? (PS the numbers on the ruler are millimetres, and also I have more photos if required but sorry they’re not better quality). many thanks in advance.

Dear Becca,
This is definitely a Rove Beetle, and it could well be
Ontholestes murinus, which is pictured on Beetles and Coleopterologists.

Hi Cassia,
This is a Rove Beetle in the family Staphylinidae.  We will attempt a species identification when we have more time.

Update:  We believe we have identified this Rove Beetle as Staphylinus erythropterus thanks to Wikimedia.

Dear Bradley,
Your image is blurry, but the contours and coloration of this Gold and Brown Rove Beetle,
Ontholestes cingulatus, are unmistakeable.  Like other Rove Beetles, Gold and Brown Rove Beetles are beneficial predators.

Saw this thing flying around my house. It landed on my couch. I trapped it in a zip lock bag. Seems aggressive…

Zip Locked Rove Beetle

Zip Locked Rove Beetle

Dear Joel,
We hope you let this Rove Beetle free after taking the digital image.  You would most likely be angry if you found yourself in a Zip Lock Bag, and you might even act out aggressively.  That said, this is a Rove Beetle, and they are truly fascinating beetles.  Their flight wings are folded and hidden beneath the small elytra, which means the Rove Beetles are softer bodied than most beetles that have elytra or wing covers which are hard and which cover the entirety of the abdomen.  Rove Beetles might be a threat to small arthropods and land molluscs, however, they pose no danger to humans as they do not possess any venom.  They do have scent glands in the abdomen and they often posture with the tail bent over the head in a position reminiscent  of the threat pose of a stinging Scorpion.  The Devil’s Coach Horse is one especially daunting looking Rove Beetle.  Your individual is not a Devil’s Coach Horse and we do not recognize your species and this is a very, very large family.

My friend saw this bug crawling in the grass around her home in central PA. She’s never seen this before and neither have I.

Dear Denise,
This is a Rove Beetle, but we are uncertain of the species.  We love the aggression of Rove Beetles, but except for the Creechies, Rove Beetles are harmless and do not sting.  Our favorite Rove Beetle is probably the Devil’s Coach Horse.  Your Rove Beetle somewhat resembles
 Platydracus maculosus which is pictured on BugGuide.

Thank you very much.  I’m glad it’s not the Creechie species!  One question though: The thorax on the bug she saw was not smooth and seemed to have a blackish/blue something on it.  Does this beetle molt?   Or perhaps it was injured and the exoskeleton is ripped partly away?

Adult beetles do not molt.  Perhaps you are seeing the flight wings which are hidden beneath the short elytra.
