Caption: Scanning electron micrograph of the head and thorax of a biting midge (family Ceratopogonidae). Biting midges are tiny, blood-thirsty flies; some species suck the blood of all warm- blooded animals, including humans, while others prefer cold-blooded animals. The long, beaded appendages (top) are antennae. Just below these are two short palps and, protruding from between them, the rod-like proboscis through which the fly feeds. Two large compound eyes (green) envelop the head almost completely. Behind the head is the front end of the thorax (visible above & below the eyes), the first pair of legs (bottom), & the wings (blue). Magnification: x60 at 6x6cm size.
