Lesser House Fly or Fannia Fly

Commonly found in and around human dwellings, barns, and poultry houses worldwide.

Larvae feed on decaying organic matter and excrement; adults feed on liquid animal waste and various liquids like nectar.

Known for a distinct jerky, hovering flight pattern, often circling in the middle of rooms or under ceiling fixtures. Males are more frequently seen performing this territorial behavior.

Generally considered a nuisance pest. They can carry pathogens due to their feeding habits on waste, potentially contributing to the spread of diseases like diarrhea or more rarely causing accidental myiasis.
