Virginia Flower Fly

Dear Dana,
This is not a Vespid nor any other type of Wasp.  This is a Fly in the family Syrphidae, commonly called Flower Flies or Hover Flies.  Many species in the family Syrphidae are effective mimics of stinging wasps and bees which helps to protect the harmless flies from predators who mistake them for a stinging creature.  We will attempt a species identification for you if we have time.  There are extensive archives on BugGuide should you decide to attempt your own research.  We believe we have correctly identified it as a Virginia Flower Fly,
Milesia virginiensis, on Insect Identification for the Casual Observer.

Wow! Thank you for the prompt reply and your expertise!
Your time is much appreciated!

Bathroom Fly

This is a Bathroom Fly or Drain Fly in the Moth Fly subfamily Psychodinae, a group that is considered an annoyance to many home owners and tenants because Bathroom Flies breed in the sludge that forms in indoor plumbing.  According to BugGuide:  “Adults often found around sewage installations, in public washrooms, and bathrooms in homes, and are attracted to light; larvae live in organic sludge that forms on inner surfaces of drains and sewage pipes; pupae occur on the surface of the organic film that the larvae have been living in.”

Subject:  Creepy Critter I’ve Never Seen Before!

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:  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.
