The relationship between feeding mode and morphology in Cheilosia larvae (Diptera, Syrphidae)

Abstract

Third stage larvae of seven species of Cheilosia are described. The morphology of each species is analysed in relation to feeding mode. A variety of features are identified that appear to be uniquely related to fungal-feeding, leaf-mining, stem/root tunnelling and sap/cambium feeding. An important factor influencing larval morphology appears to be the solidity of the food. A relationship between morphology and feeding mode should be useful in analysing the larval stages of other Cheilosia species, the majority of which are unknown.
