Cordylobia is a genus of fly from the family Calliphoridae. The larvae of Cordylobia are parasitic on mammals, especially rodents. Two species, C. anthropophaga (the tumbu fly) and C. rodhaini (Lund's fly), also are known as parasites of humans. The adult flies feed on rotting fruits, vegetables and animal faeces, and are most abundant in the wet season. like many tropical insects they are most active in the morning and evening. Cordylobia are largely confined to Africa, though they have been recorded elsewhere when transported by human travellers.
