bug found in the mens washroom at work
July 13, 2010
Hello – a very silly request so I apologize in advance – but there’s a fly in one of our washrooms here at work that i’ve never seen before. Googling does not get me the results I hope for.

Bathroom Fly

Dear Bored at work,
We wondered if perhaps the problem you had identifying this Bathroom Fly (yes that is its name) had anything to do with the semantics of the word “washroom” as opposed to bathroom, so we did a search of “fly” and “washroom”.  On the first page of possibilities was a website with an image of your creature.  Bathroom Flies in the subfamily Psychodinae are also known as Moth Flies, Drain Flies, Sewage Flies or Filth Flies according to BugGuide.

Caterpillar like larvae

Recently we submitted a photo which was identified as a moth fly. Thank you for the prompt reply!
The same customer has submitted another photo which looks like some type of larvae. (perhaps the moth fly?)

Moth Fly Larvae

Hi again Cathy,
Based on images we found on the Integrated Pest Management Resources website and on BugGuide, we believe these larvae are immature Moth Flies.

Big Winged Fly in Worm Bin
March 4, 2010
One of our customers has sent the attached photos of their worm bin.
The conditions in the worm bin are very wet, (muck like). These tiny, big winged flies are very numerous covering the surface of the worm bin. Red wigger worms are numerous also and seem not to be affected by the winged creatures. They look like alien flies. Please let us know what we have here.

Moth Flies

Hi Cathy,
These are Moth Flies in the family in the subfamily Psychodinae.  There is an excellent close up photograph on BugGuide.  Certain species breed in drains indoors, and they are commonly called Bathroom Flies or Drain Flies.

Bathroom Fly

Hi shayni,
THough it resembles a moth, this Bathroom Fly is really a fly in the subfamily Psychodinae, the Moth Flies.  There are genera in the subfamily that look alike, and BugGuide pictures many species found in North America.  Bathroom Flies or Filter Flies as they are also called are often found indoors in damp bathrooms because they breed in the muck that accumulates in plumbing.

We’ve started seeing a number of these critters in our bathtub. They are 3-5 mm in length and are extremely fragile. I did this guy in trying to get him under the scope, so I don’t have a better pic. It has been a very wet fall here in northeast GA and I suspect the water is driving them to higher ground. They are driving the wife nuts and need to find out what they are and how to get rid of them.

Bathroom Fly Larva

Bathroom Fly Larva

Dear Jim,
We believe this is the larva of a Bathroom Fly or Drain Fly which is pictured on BugGuide.  They are also called Moth Flies and are in the subfamily Psychodinae.  The tiny mothlike adults are frequently found in bathrooms, and the larvae live in the drains.

Moth like insect

I found this insect sitting on my wall. It is about 2-3 mm in length. I took my camera and clicked this snap. I am not able to identify this one. Appreciate if you can help me to find this out.

Dear Sanjay,
This could well be the most detailed image of a Bathroom Fly, Clogmia albipunctata,  we have ever received.  According to Charles Hogue in Insects of the Los Angeles Basin:  “The Bathroom Fly is often noticed indoors in damp areas – on the walls of bathrooms, showers, lavatories, and washrooms.  The brown worm-like larva develops in the sludgy organic muck that accumulates outdoors in shallow pools and tree holes and, under artificial conditions, in sink traps, drains, and dead-flow areas in the household plumbing.”  Your observation that this is a Moth like insect is right on since the family Psychodidae, is know as the Moth Flies.

Thanks so much Daniel. The information was helpful. I do photography as my hobby and just love macro photography. Will definitely use your website for any bug identification. Your site is of great help.
