[1] It is a Balkan-Anatolian species distributed throughout the Balkan peninsula, specifically found in Bulgaria, East Thrace, Greece, and North Macedonia[2] and in Turkey.

[3] They inhabit forests and open grasslands, with flights near river gorges as well.

Nemoptera sinuata is primarily diurnal, the flight period lasts from mid-May to late June.

Studies have shown that N. sinuata primarily feeds on the pollen of Alyssum murale, Cota austriaca, and Achillea coarctata.

The larvae are unusual for other lacewings in that they are primarily herbivorous, rejecting other insect prey in favour of water and vegetable sap.
