Subject:  Creepy Critter I’ve Never Seen Before!
Geographic location of the bug:  Madison County, Kentucky

Time: 11:26 PM EDT
Your letter to the bugman:  My boyfriend and I walked into the kitchen around 10:45 pm and next to the sink was an insect I was creeped out by, but couldn’t stop looking at!
It didn’t move when the boyfriend removed it to the bathroom. I am not sure if it was dead or alive.
Both of us have lived in old houses before and never seen one….we are both in our 40’s.
The house we live in now in on the foothills of the Appalachia Mountains. It was built in the late 1800’s and renovated in the 1940’s and again in the 1960’s.
The original creek rock, used in original foundation, is still under the house.
There are also many caves around the area. As well as other “creepy” types of bugs. Example…. Cave Crickets.
The weather has been a lot milder, wetter, and, cooler than normal.
Are these normal for this area? I can’t find anything about them.
Thanks so much!

Robber Fly

Dear Concerned in Kentucky,
You have no cause for concern.  This is a Robber Fly, a winged predator that did not originate from inside your home.  It likely accidentally entered the home and died.  This is an outdoor predator that has no interest in living indoors.  We cannot tell the species for certain but we believe it might be a Hanging Thief in the grnus
Diogmites which is pictured on Bugguide.

Your letter to the bugman:  Found this guy in a shallow puddle. It was interesting how it flung it’s back end to “swim”.

Your letter to the bugman:  A couple days ago I noticed dozens of these guys all over my deck, cars, and front of house. Not sure where they came from or what they are. Any ideas would be greatly appreciated. Thanks in advance.

March Fly

Dear Bryan,
This is a March Fly in the family Bibionidae and probably the genus
Bibio.  They often appear in great numbers and then just as suddenly they will be gone.  According to BugGuide:  “Adults emerge synchronously in huge numbers and often form dense mating aggregations. Males form loose “swarms” and copulate immediately with females as they emerge from the soil. After mating, female bibionines dig a small chamber in the soil with their fossorial fore tibiae, lay eggs, and die within the chamber (Plecia lay eggs on the soil surface). Adults are short-lived (3-7 days).”

Thanks for the quick info and links. Now at least I know what I’m dealing with. Hopefully they disappear again soon.
All the best,

Subject:  What’s this bee, hornet, wasp?
Geographic location of the bug:  Southwestern pa. South of Pittsburgh

Your letter to the bugman:  At a local playground South of Pittsburgh pa. This thing was on the sign. The larger bug was between 1 and 1.25 inches long not including legs. It appeared to be eating/mating with a “normal” sized bee/wasp. Is this one of those “murder hornets”? I haven’t heard of them in this area yet… Or is this just some large wasp… Thanks for any info.

Red Footed Cannibalfly Eats Wasp

Dear The Robe,
This is neither a Bee, nor a hornet nor a wasp.  It is a Red Footed Cannibalfly, a predatory Robber Fly that feeds on large flying insects, including bee, hornets and wasps.

Horse Fly Larva

Dear Sonja,
This sure looks like a Horse Fly larva to us, and we have received numerous reports this summer of Dark Giant Horse Flies from the UK here, and here, so it makes sense that this is the larva of a Dark Giant Horse Fly.

Your letter to the bugman:  Hi
Spotted this apparently resting on the ground and wondering what it is. Don’t think I’ve ever seen the like.
Can you help?

Hornet Mimic Hover Fly

Dear John,
This is a Hornet Mimic Hover Fly,
Volucella zonaria, a harmless species of Fly that benefits by mimicking stinging insects.  According to Wildlife Trusts:  “At almost 2cm long, the hornet mimic hoverfly is the largest hoverfly species in the UK. As its name suggests, it is an excellent mimic of the hornet, but is harmless to humans. Only a very rare visitor to the country up to the 1940s, it has become more common in Southern England in recent years, and is still spreading northwards, perhaps as a result of climate change. It is particularly prevalent in urban areas. The adults are migratory and the larvae live inside wasps’ nests.”

Thank you so much for that. We were intrigued about the strange insect.
You have been most helpful.
