Scanning electron micrograph of the head of the fruit fly Drosophila melanogaster. This is the normal, wild type of the fly, known as Oregon R. It is widely used for genetic experiments, particularly on mutation, because it is easy to raise in large numbers & reproduces rapidly. The waist between the head & thorax is character- istic of flies, allowing some mobility. Two large compound eyes are visible on either side of the head. The ocellus, or simple eye, is visible as 3 raised spots on top of the head. The antennae are the small fleshy pads with bristle-like extensions called aristas. Bristles, or setae, cover the fly. Magnification: x200 at 8x10 inch size. 8x10-inch size.
