What are flesh flies?
The calyptrate family Sarcophagidae (Diptera: Oestroidea) includes 65 species occurring in the British Isles. These include the well known "flesh flies" in the genus Sarcophaga, medium to large sized flies with tessellated patterns on the abdomen. Sarcophaga species are frequently seen basking on sunlit fences, rocks and other structures. They also engage in "summiting" at hilltops and other high points in landscapes.
The family contains three subfamilies:
Miltogramminae: Kleptoparasites of solitary wasps and bees, sometimes known as "Satellite flies" from the habit of some species of closely following host species back to their nests.
Paramacronychiinae: Flies with a diverse biology ranging across necrophagy and predation of snails to parasites or parasitoids of mammals and insects.
Sarcophaginae: The typical "flesh flies" described above. Their biology is very varied and includes predators and parasitoids of various insects, breeding in animal faeces, carcasses, dead snails, decomposing organic matter. The biology of many species is poorly understood or completely unknown.
