Gray flesh fly

,

Sarcophaga carnaria

The gray flesh fly measures 10-16 mm, is slender and the abdomen is checkered with light and dark gray spots. The larvae develop into adult flies in feces and on animal carcasses. Preys on protein-rich foods such as meat, cheese and fish. But also seeks out animal carcasses and excrement in the wild. The alternating stay on carrion, feces and food is not only unappetizing, but also makes this fly a carrier of harmful germs and a source of questionable contamination of food.

Large housefly

,

Musca Domestica

The housefly is black, 7-8 mm long, its proboscis is directed downwards and ends in the easily recognizable sucking pad. The inner edges of the wings overlap when at rest. The female lays about 600 eggs mainly in dung, faeces, compost heaps and garbage heaps, i.e. wherever organic matter decomposes. This fly has a preference for human and animal bodily excretions (sweat, feces, festering wounds) and thus transmits infectious diseases such as typhus, cholera, salmonellosis, polio, foot and mouth disease, etc.). Home furnishings and food are soiled and may be contaminated with pathogens.

Blue flesh fly

,

Caliphora erythrocephala

The flesh fly is about 10-14 mm long, heavily bristled, predominantly black with bluish longitudinal stripes on the thorax and a dark blue shiny abdomen. Over 1000 eggs are laid in individual piles on protein-rich substances, e.g. meat. The white maggots often hatch on the same day.
