Silkworm. Coloured scanning electron micrograph (SEM) of the head of a silkworm moth caterpillar (Bombyx mori). The silkworm uses its chewing mouthparts (upper centre) to feed on mulberry leaves. On either side of the mouthparts is an antenna and several simple eyes (ocelli, black round structures, upper left and right). The caterpillar has three pairs of jointed legs behind the head (lower centre). Most caterpillars also have prolegs further along the body (not seen). The silkworm produces threads of silk with which it constructs a cocoon. People farm silkworms for their silk, which is woven into cloth. Magnification: x25 when printed 10cm wide.

Tobacco hornworm with tobacco plant
Tobacco hornworm (Manduca sexta) with a damaged tobacco plant, artwork. This species is common throughout North America. Eggs (right, lower) are laid on the underside of the leaves of the tobacco plant (Nicotiana sp.). These hatch into larvae (right, second from bottom) that feed on the plant. Although the nicotine in the leaves is toxic to many organisms, the hornworm larvae are able to sequester and secrete it. The damage to the plant by feeding larvae can be seen on the lower leaves. The larvae bury themselves in the ground to form a pupa (right, second from top). After about 18 days the adult moth (right, top) emerges.
