Caption: Black fly. Coloured Scanning Electron Micrograph (SEM) of a Black fly, Simulium sp. Also known as the buffalo gnat, this parasitic, blood-sucking insect is closely related to mosquitoes. The head possesses two compound eyes (green), short segmented antennae and skin-piercing mouthparts. Its poisonous bite and blood-sucking habits cause irritation and sickness to humans, and serious injuries and fatalities to cattle and horses. Certain species like Simulium damnosum in Africa transmit the filarial worm Onchocerca volvulus which causes river blindness. Black flies are distributed worldwide. Magnification: x10 at 6x7cm size.
