The biology of B. scopigera was investigated under laboratory and natural conditions, and Onobrychis viciifolia infestation was determined in field experiments conducted in Erzurum, and districts of Askale, Ilca, Pasinler and Tortum, Turkey during 1994-96. The growing periods of different biological stages of the insect were determined. The insect overwintered in cocoons in the roots of sainfoin during the larval stages except during the first stage. The larvae started feeding from mid-April and eclosed at the end of June. The first eggs were laid at the beginning of July. After 10-14 days, the hatched larvae started feeding, entered into crowns through cracks, splits and buds of the plant, and overwintered starting in September.
