Biology: The white larvae develop gregariously in leaf rolls on Populus tremula, rarely also on other Populus species ( Salicaceae). Our records are all from P. tremula . Infected leaves are rolled upwards along their margins and tend to be abnormally hairy. Multivoltine; pupation and hibernation in the soil.

Distribution: Widespread in Europe including Norway, Sweden, Denmark and Finland. Central Siberia.
