They are active at dusk and later come to light.
The adults fly in two generations a year from late May till July, and a partial second generation in August-September/October.
The larva lives on Pinus sylvestris, Abies alba and other coniferous trees like Picea, Larix, and even sometimes Juniperus.
It occurs in and around conifer plantations.
