Abstract

The functional morphology of the feeding apparatus of 12 species of carabid beetles from 8 tribes has been studied. This has been correlated with the gut contents and the ability of some individuals (particularly Carabitae) to produce digestive fluids pre-orally to aid digestion. A wide range of species exhibting diverse feeding habits has been investigated; it includes both those Carabinae which are strictly carnivorous and those which are mainly herbivorous. Thus a basis has been established which enables the feeding methods of carabid beetles, which are relatively little known, to be better understood.
