About

The flesh fly, scientifically known as Sarcophaga carnaria, is commonly found worldwide and often seen in gardens. It gets its name from its tendency to lay its eggs on decaying flesh, including animal carcasses. While they can be mistaken for houseflies due to their similar appearance, flesh flies are distinguishable by three stripes running down their thorax and a checkerboard pattern on their abdomen. They can range from 6 to 14mm long and have large red eyes. Interestingly, female flesh flies nurse their young with milk-like secretions until they are old enough to feed on carrion. Despite their association with death and decay, these insects play a vital role in maintaining ecological balance.
