About Hemichroa australis (Serville, 1823)
Hemichroa australis (Serville, 1823) is a species of sawfly. Adults reach an approximate body length of 7 to 8 millimetres, which equals 0.28 to 0.31 inches. The head and thorax of this sawfly are bright red, while the mesopleuron and abdomen are shiny black. This species closely resembles Hemichroa crocea, which differs from Hemichroa australis by having a bright orange abdomen and legs. The larvae of Hemichroa australis feed on plants from Alnus (alder) and Betula (birch) species. This sawfly can be found across most of Europe.
