| Abstract: | Rearing data from higher plants, carrion and bird and mammal nests and burrows are provided for eight species of Heleomyzidae (Diptera): Heleomyzinae: Heleomyza borealis Boheman, Scoliocentra brachypterna (Loew) and Eccoptomera microps (Meigen); Heteromyzinae: Tephrochlamys flavipes (Zetterstedt), Tephrochlamys tarsalis (Zetterstedt) and Heteromyza rotundicornis (Zetterstedt); and Suillinae: Suillia ustulata (Meigen) and Suillia variegata (Loew). The puparia of these species are described. Unique characters and characters in combination distinguish each species and their subfamilies, suggesting that early stages are a valuable source of taxonomic data. Head skeleton and other features suggest contrasting food gathering mechanisms, with heleomyzines suited to feeding on food of low viscosity, suillines on high-viscosity or firm food and heteromyzines on food of intermediate viscosity. |
