Morpho-Ecological Characteristics of Immature Stages of Xylobiont Species of the Genus Phaonia Robineau-Desvoidy, 1830 (Muscidae, Diptera) Inhabiting Tree Holes and Sap Accumulations

Abstract

The biology of immature stages of the Diptera that accompany xylophagous insects inhabiting sap runs and tree holes was studied. Biological data are reported for the first time for 4 species and supplemented for 2 more species of the genus Phaonia Robineau-Desvoidy, 1830 (Muscidae). The main diagnostic characters of these species are given. The species differ in the life history of larvae, the morphology of the anterior and posterior spiracles, creeping welts, cephalopharyngeal apparatus, and anal plate. A key to immature stages of xylobiont species of the genus Phaonia is compiled.
