What is the number of generations the European Sawfly produces each year?

The European Sawfly typically produces one generation each year. This single generation cycle aligns with the life cycle of many sawfly species, which involves wintering as a pupa and then emerging in the spring to feed on host plants. The larvae tend to become active during a specific time when conditions such as temperature and food availability are ideal, and they complete their development in a single season. As a result, understanding this singular generation pattern is crucial for effective pest management and control strategies, particularly for those involved in turf and ornamental horticulture.
