Abstract

The feeding behavior of insects changes, often radically, according to their stage of development, with individuals in different developmental stages differing as regards amounts and, often, the kinds of food they eat. It is well known, for example, that the larvae and adults of most holometabolous insects have very different feeding behaviors and diets. Perhaps less widely recognized are the less striking, but nonetheless still substantial, changes which can occur during larval development, both within and between instars, and during adult life in relation to stages of somatic and reproductive development and to the level of an insect’s reproductive activity.
