Feeding

Adapting to life in the most varied environments, Insects have learnt to exploit every food resource that the environment itself offered them: there is practically no organic matter that is not sought after by at least one group of them. Because of this enormous variety of diets, the mouthparts have undergone, in the course of evolution, a series of adaptations that have profoundly modified the primitive structures. The main types of mouthparts are: chewing, sucking, and piercing-sucking.

CHEWING: Orthoptera, Coleoptera, Neuroptera, many Hymenoptera and Lepidoptera larvae.

PIERCING-SUCKING: Ditteri.

SUCKING: Hemiptera, Lepidoptera, Ditteri.
