Hornet head. Coloured scanning electron micrograph (SEM) of the head of a European hornet (^IVespa^i ^Icrabro^i). The compound eyes are on either side of its head, with two antennae branching off to left and right from between the eyes. The biting jaws (mandibles) are at lower centre. Part of the rest of the body, the wings, and two legs, make up the rest of the image. This hornet is the largest of the European wasps, and has a reputation for being aggressive, though it only stings if provoked. Magnification: x10 when printed 10cm wide.
