Biology. The number of generations varies from 1 to 3 according to the latitude and the climate but sometimes it can develop without diapause, the generations overlapping ( Saulich & Musolin 2009). According to the season, the host plants change ( Saulich & Musolin 2009). In Norway the overwintering adults become active in mid May, the adults of the new generation appear from the end of July to the beginning of August and larvae can be found until mid August. Overwintering females are fertilized and those of new generation can reproduce only after exposure to low temperature ( Saulich & Musolin 2009). It has been demonstrated that the first generation feeds upon preys though the second feeds on herbs ( Saulich & Musolin 2009).
