About Macrophya punctumalbum (Linnaeus, 1767)
Macrophya punctumalbum can reach a length of 10 millimetres, or 0.4 inches. Females of this species have a basic black body color. Their legs have bright red hind femora, while the tibias are black with a white apex. The tergites display three to seven white spots on both sides, and there is a large white spot covering most of the scutellum. This species shows clear sexual dimorphism. Males are much smaller than females, and are completely black. They are very rare because this species is substantially parthenogenetic. Larvae develop on the leaves of plants in the Oleaceae family, including the genera Fraxinus, Ligustrum, and Syringa. Adult sawflies of this species can most often be found from May through July. Adults mainly feed on pollen and nectar. This species is widespread across most of Europe, extending as far east as the Caucasus.
