Life history and Habits:
The Oblique banded Leafroller undergoes a complete metamorphosis, with four distinct life stages: egg, larva, pupa, and adult. The larvae of this moth feed on the leaves and fruit of host plants, creating nests that protect them from predators and adverse weather conditions. The pupae of this moth are found in silk cocoons within the nest. The adult moth emerges from the pupa in the late spring or early summer months, mates, and lays eggs on the leaves and fruit of host plants. The life cycle of the Obliquebanded Leafroller takes approximately one year, with multiple generations per year in warmer regions. Using insecticides and integrated pest management strategies can help control populations of this pest.
