Life cycle and appearance of Pea moth

The adults have a wingspan of 12-16 mm and olive brown forewings with black and white bands on the margins. The larvae measure 13-18 mm when fully developed They are initially white and later turn yellow with dark dots at the base of the hairs and a brown head.

The adults lay eggs on flowers or leaves of pea in June and July. Eggs hatch after 1-3 weeks and the larvae bore into the young pods and feed on the seeds for about 3 weeks. Thereafter, they leave the pod to overwinter in a cocoon in the soil. Pupation takes place in spring and the adults start to emerge in May.
