Bradysia coprophila

Resource Type
Common Name

The adult fly is small, up to 3 mm, has a dark brown body, small head and its legs and wings are comparatively long, looking like a mosquito. These insects feed on decaying organic matter and fungi. They are often found in greenhouses. Their larvae are up to 6 mm long, white, slender and legless, with a black head and smooth semi-transparent skin which reveals the contents of the digestive tract.

Sex determination in Sciara is a different mechanism. Sciara basically has 4 pairs of chromosomes 3 pairs of autosomes and one pair of allosomes. Some special chromosomes called limited chromosomes are present in certain stages. The zygote has 3 pairs of autosomes a one or more limited chromosomes and 3 X chromosome (2 fathers’, 1 mother's).
