Phorid Fly

 

Color: black, brown or yellowish
Legs: 6
Shape: oval with a humpbacked appearance from the side
Size: 1/16" to 1/8"
Antennae: Yes
Region: Found throughout U.S.

 

The Phorid Fly, also known as humpback flies, resembles fruit flies in appearance.  The Phorid fly lacks the red eye color that is the classic trademark of the fruit fly.  A Phorid Fly can often be identified by their escape habit of running rapidly across a surface rather than immediately flying when disturbed. .

 

Habits

 

A Phorid Flies flight pattern is characteristically short and erratic.  Adults have a peculiar habit of rapidly running across windows, TV screens, tables, walls and plant foliage.

 

Habitat

 

Phorid flies are fairly common in many habitats, but are most abundant about decaying plant and animal matter.  In structures, these flies can be found breeding wherever moisture exists around plumbing and drains in bathroom and kitchen areas, garbage containers, garbage disposals, crawl space areas and basements.  These breeding areas are occasionally very difficult to locate.

 

Threats

 

Because Phorid flies breed wherever moisture exists, the presence of Phorid flies can indicate that a serious plumbing issue exists.

 

Prevention

 

Eliminate the plumbing or moisture issues in the home as well as keeping drainage pipes clean.
