Flying Insects

FERMENTATION FLY

They are also called vinegar or fruit flies. They so named because they like naturally fermented foods. They will be attracted to fermenting fruit, moist bread, sweet syrup and alcohol. So they are most likely hanging out in fruit and vegetable stores, bakeries and bars. They are many in summer and autumn which is the time when fruits and vegetables are harvested.

They are about 3 – 5 mm long at adulthood. They are dullish yellow – brown to brownish – black in color. They have red eyes and the head and thorax are tan in color. Their abdomen is gray or black. Their eggs are pearly white, and larvae are cream in color measuring 2 to 5 mm in length. Adults are quite fast and can travel for up to 6 miles in the span of 24 hours.

They are quite prolific in breeding and have a life cycle that can take as little six days. Females lay up to 2000 eggs in their lifetime and they do this close to fermenting food. Their eggs hatch in 24 to 30 hours and the larvae feeds on the fermenting food for a minimum of five days and crawls out only to go to drier areas to pupate.

Emerging flies can become sexually active in two days time. The presence of fermentation flies can be identified by their feces, which are brown spots everywhere. Females like to go to wet areas to lay their eggs and can be found in drain systems, waste bins with organic waste and moist cleaning equipment.
