Your letter to the bugman :  Kinda a scary bug. Not sure if it’s a wood eater looking to destroy my house?  An earwig?  Does it bite or sting?  He kept circling me and landing near me and chasing me. Maybe he just had a missing antennae and couldn’t steer

Gold and Brown Rove Beetle

Dear C,
Few people would recognize this as a Beetle, because it does not resemble most beetles.  This is a Gold and Brown Rove Beetle,
Ontholestes cingulatus, which is pictured on BugGuide.  According to BugGuide:  “Eggs are laid near carrion or fungi; pupate in chambers in soil nearby”  It will not harm your home.

Your letter to the bugman:  I found this little guy scurrying on the basement floor of our house. For a moment I thought it was a caterpillar and was going to stomp on it, but I realized he was not going to become a moth and took some pics. I’m pretty sure this is some sort of beetle but I’ve never seen one like this before! And FYI once I took these pics I let him go outside. I am of the same mind with respect to most bugs 🙂

Your letter to the bugman:  This odd creature flew into my phone, bounced off & landed in front of me. It then proceeds to waggle it’s purplish wings & tasseled abdomen at me before retracting it’s wings (somewhere!) Only to produce them once again & promptly take off. It’s a hot and steamy August here in Virginia. I’ve been a keen observer of nature all of my life & can honestly say, this one has stumped me completely. Hope you guys can help me out!

Rove Beetle

Dear Holly,
You have good reason for being stumped.  This is a Rove Beetle in the family Staphylinidae, and many members of the family look very different from the “typical” beetle.  Unfortunately, BugGuide is currently experiencing technical difficulty and we cannot search for the species, but luckily, we were able to identify it as 
Platydracus maculosus in Beetles of Eastern North America by Arthur V. Evans where it states it is:  “the largest rove beetle in North America.”  The image with its abdomen curled up is a typical threat posture for many Rove Beetles.

Rove Beetle

Dear Crystal,
Based on this BugGuide image, we believe we have correctly identified your Rove Beetle as
Platydracus immaculatus.  Rove Beetles are not aquatic.  We believe this individual fell into the pool.  According to BugGuide:  “now infrequently collected over much of its range.”

Your letter to the bugman:  Bug was found in lawn when removing african beetles.
Is over 6mm in length.
Wondering what the beetle is and if it is destructive to plants or harmful to pets

Devil’s Coach Horse

Dear Daniel,
Because of its red head, this is an amazing looking Rove Beetle in the family Staphylinidae, and we identified it as
Creophilus erythrocephalus, commonly called a Devil’s Coach Horse, thanks to images on Wild South Australia.  According to Museums Victoria:  “Devil’s Coach Horses eat maggots (fly larvae) and are usually found living in rotting animal carcasses.”  While that might seem unsavory, we would consider them beneficial as they help to control Fly populations.  The species is also pictured on Atlas of Living Australia.  The common name Devil’s Coach Horse is also used with a European species of Rove Beetle that has naturalized in North America.  This Devil’s Coach Horse does not look like it died of natural causes, so we are tagging this posting as Unnecessary Carnage.

Your letter to the bugman:  We are finding many of these bugs in cat litter boxes at the cat rescue center where I volunteer.  They are small,  skinny and maybe 1/4 inch long.
Thank you.

Rove Beetle, we believe

Dear Christine,
We wish the quality of your image was better.  Though it somewhat resembles an Earwig, we believe, based on this BugGuide image, that this is a Rove Beetle, but the species is not identified.  Regarding finding them in proximity of litter boxes, BugGuide indicates:  “Often found under rocks, logs, etc. Some found on edges of bodies of water, others on carrion, decaying fungi, etc” and “Most adults and larvae are predatory on other invertebrates. Some larvae feed on decaying vegetation.”
