Hello bugman, me an my girlfriend were out on an adventure flipping rocks and logs when we came across this little guy. I’ve been flipping rocks for many years now and don’t recall ever seeing this type of insect. When it moved it had its rear end in the air.

Rove Beetle

Dear Kevin & Amber
This is a magnificent Rove Beetle.  We started by searching through Arthur V. Evans excellent book Beetles of North America where we identified this Rove Beetle as
Platydracus maculosus, a species that unfortunately has no common name.  Evans writes:  “the largest rove beetle in North America. … Adults active spring and summer, attracted to carrion, decaying fungi, and dung.”  Here is a BugGuide image for comparison.

Unknown Rove Beetle

Dear Jacquie,
This is not a Cockroach.  It is a beneficial, predatory Rove Beetle in the family Staphylinidae, but alas, we have not had much luck determining a species name.  There are many species of Rove Beetles illustrated on NatureSpot, but none that looks quite like yours.  According to Mark Telfer’s Website:  “There are about 1,134 species in this family, as delimited in the Duff (2012) checklist. This one family thus contains over a quarter of the 4,072 species of beetle.”   We believe those statistics refer to the British Islands.

I need help identifying this bug. Found in Richmond Virginia on 2/12/17 on a warm afternoon. Usually I can find the bug through the internet, but not this time.

Brown and Gold Rove Beetle

Dear Phil,
You really didn’t need much help.  Most people don’t even recognize Rove Beetles as Beetles.  We believe this is either a Gold and Brown Rove Beetle,
Ontholestes cingulatus, or a closely related species.  We really like the Ozark Bill A Thousand Acres of Silphiums page.

Subject: Strange bug from Portugal

Hi, bugman.
Found this strange bug hanging around my backyard in Portugal, never seen one before. My cat chased it into the house. It’s nearing the end of winter now.
I’m of course wondering what it is. When the cat was trying to swat it around, I noticed it attempts to raise its tail like a scorpion and secretes a white liquid from the tip. A stinger of sorts, I presume?
The bug was of course released without harm.
Anyway thanks in advance for any help!

Devil’s Coach Horse

Dear David,
This native predatory Rove Beetle in the genus
Ocypus is commonly called a Devil’s Coach Horse.  They are not dangerous to humans, though they are able to expel a foul smelling odor from glands at the tip of the abdomen which they do while striking a curious curved posture that many folks liken to the appearance of a stinging scorpion.  This European native has naturalized in parts of North America and according to BugGuide:  “They often eat, and may help to control, the introduced brown garden snail.”

Hey Bugman,
On a recent trip to Borneo we came across this funky bug.
Very praying mantis in its stance, but flies like some sort of wasp.
Super cool creature that we spent about 30mins watching as it waited for ants or flys to cross its path so it could have lunch.
Thanks!

Rove Beetle

Dear Emily,
The front legs on your insects are quite unusual, and they do not seem adapted for walking.  Nonetheless, we are relatively certain that this is a Rove Beetle in the family Staphylinidae.  But for the front legs, your individual looks like this individual from Malaysia pictured on Project Noah.  This unidentified Rove Beetle from Paul Bertner’s Rainforest Photography site and the one from Borneo Bootcamp have similarly structured legs.  Because we will be away from the office for the holidays, we are postdating your submission to go live at the end of the month while we are away.
