Description
Macrophya punctumalbum can reach a length of 10 millimetres (0.4 in).[2] In the females the basic body color is black. Legs have bright, red hind femora, while tibias are black with white apex. Tergites shows three to seven white spots on both sides. There is a large white spot over most of the scutellum.[2]
This species shows an evident sexual dimorphism. Males are much smaller than the females and completely black. They are very rare, because the species is substantially parthenogenetic.
The larvae develop on the leaves of Oleaceae species (Fraxinus, Ligustrum, Syringa).[2][3]
The adults of this sawfly can mostly be encountered from May through July. Adults mainly feed on pollen and nectar.[4]
