False colour scanning electron micrograph (SEM) of the head of a hairy desert-field ant Formica pilicornis, showing the two compound eyes (on top of head at left and right) and between them two antennae, which articulate with the head in ball & socket type joints. The mandibles - mouthparts (bottom of head) are used as all-purpose tools and weapons. Most ants live in a social system that demands great collaboration of its members. An example involves the exchange of food from older foraging worker ants to younger workers who look after larvae and reproductive ants. Magnification: X 23 at 35mm size.
