Rove Beetle

Dear J Powell,
Wow, is Warwickshire a portal to the future???  Found in 2015???  This is a beneficial Rove Beetle in the family Staphylinidae, but we are uncertain of the species.  According to BNHS YounGnats:  “There are over 1100 different rove beetles in UK.”  According to the Empire Pest Control site:  “This casual intruder is associated with the forest environment for the whole of it’s life, however they do enter homes seeking shelter. Common in UK around field and forestry areas. Are not known for feeding on regular household food stuffs. Despite their somewhat aggresive appearance they pose no threat to people.”  The description continues with:  “What this predator is really looking for are insects, small invertebrates. It also catches maggots and other insect larvae. Will also feed on old decaying forest mushrooms and escaping sap on tree trunks.”
  We don’t really want to know why your individual appears bent into an unnatural position, though we suspect Unnecessary Carnage.

Hi Joeran,
This is some species of predatory Rove Beetle in the family Staphylinidae and it will not harm you or your home.  You should release it from its plastic bag immediately.  It looks like a very good match to this image of
Creophilus maxillosus on Warren Photographic Image Library of Nature & Pets.  According to BugGuide, it is called a Hairy Rove Beetle and it is:  “native and widespread in NA, C. m. maxillosus is native to the Palaearctic and is known from scattered records from ON, QC, and MA (first detected: ~1620, NF)(2) and many other parts of the New World” which indicates there are different subspecies in the Old and New Worlds.  We learned that there is a European subspecies, Creophilus maxillosus maxillosus, and according to Nature Spot, it is:  “Widespread and generally common throughout Britain.”  According to BugGuide, the Hairy Rove Beetle feeds on “maggots and adult flies, also other arthropods,” so it is a beneficial species.  Eakringbirds has a UK distribution map.  Macro Photos has an image taken in Norway.  Gwannon.com has a worldwide distribution map that includes Norway.

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.
