Subject: What kind of fly is this?
Location: Illinois

These are flying all around in our my apartment buildings hallway. They have been following me in and I now have them flying around my apartment. They don’t seem to fly a lot though. They tend to land and then dart around really fast. This has made them fairly easy to kill. I have never seen flies like these before and am not seeing them online anywhere. I have noticed that when I kill one a very small reddish orange bug comes off of it. The last one I killed had two of these tiny bugs crawl out or off of it. I have had a hard time getting a good pic of these but I have attached the best one I have. Any info you have would be much appreciated as I am so sick of dealing with these things.

Humpbacked Flies

Dear J Crellin,
We will be checking with Eric Eaton for assistance on this identification.

Yes, Daniel, those are humpbacked flies, family Phoridae.  Probably Megaselia scalaris, by far the most abundant indoor species.  They feed on decaying matter as larvae, so you find them mostly in the kitchen, around the garbage disposal, etc.

micro bugs living in house, stinging for 2 years!
October 3, 2009
Neighbor kid went to Florida. Kid brought back invisible stinging bugs (not bedbugs). Neighbor kid came to visit and brought her stuff and then we were both infested. They got rid of them with kerosene after a long struggle. I am afraid of using kerosene and gasoline in my house. OTC pesticides are ineffective. They only bite me and my one daughter.

Scuttle Fly

Dear No sleep in TN,
In our humble opinion, you should not blame the neighbor kid for this situation.  It looks to us like you have Biting Midges in the family Ceratopogonidae, which are also called Punkies or No-See-Ums because of their tiny size.  Since they are so small, they can enter homes through the mesh in window and door screens.  According to BugGuide, they are found near “salt and freshwater marshes, forests, edges of ponds and streams.” and “larvae develop in moist or wet sand, mud, and decaying vegetation of salt and freshwater marshes, ponds and streams.”  They would not be breeding inside your home, so they are entering from the outside.  BugGuide also indicates:  “Many species, mostly in Culicoides, bite humans and can be very annoying.
“  We will contact Eric Eaton to see if he concurs with our identification and our conclusions about the source of the problem.  Tennessee is part of the normal range for Biting Midges known as No-See-Ums.

UPDATE
addendum to micro bugs living in house, stinging for 2 years!
I took the shots with a 100X microscope, so the wasp looking insect is very tiny. It also has a larval form that is round and white with feelers and a pupa from which the black “wasp” hatches. All very tiny.

Correction from Eric Eaton
Daniel:
Thanks to the outstanding close-up images, I can easily tell that the “no-see-ums” are actually non-biting flies in the family Phoridae (“scuttle flies“).  The larvae breed in decaying organic matter.  So, unless the neighbor kid brought spoiled food into the home, he is not to blame.  Phorids can be abundant in just about any home.  I have had them surviving on residue in the kitchen sink garbage disposal.  Since they do not readily carry diseases, and they do not bite, I don’t pay much mind to them.  Simply discarding whatever decaying matter they are infesting should end the problem immediately, or very quickly.
