What are Phorid Flies?

Phorid flies are commonly known as ‘Humpbacked Flies’ because of their humpback shaped thorax, and resemble fruit flies due to its small size ranging between 1.5 mm to 3mm, dark brown color, and red eyes.

They are seen mostly during the summer season and can be found near unhygienic or moist places such as basements and pipes. They feed on decaying organic matter and moist food found in damages containers or bins.

The main difference between adult phorid flies and other flies is that when adult phorid flies feel threatened, they start to roam quickly on the surface, due to which they are also known as ‘Scuttle Flies’. Whereas, other flies immediately fly away to a safe place.

The average lifetime of a phorid fly is 14 to 37 days during which it undergoes the following different stages of the life cycle: egg, larval, pupal, and adult.

Phorid flies lay around eighty eggs per day near decaying organic matter. The eggs hatch in to larvae within two weeks and stay near moist, decaying matter.

The larvae start crawling towards dry areas to pupate and then transform in to adult phorid fly, depending on the temperature and environmental condition of that place.
