A fairly common species in the northern part of Belgium, much rarer in the south. Can be locally a pest on various Leguminosae, especially on cultivated peas.
Native
The adults fly between May and August, with the peak in May and June.
The larvae living on Pisum sativum.
The larvae living in a pod of the food plant, feeding on the green peas. They move from seed to seed, often uniting two together with a silken web. When it's fully fed, it cuts a hole in the side of the pod and drops to the ground. Here it constructs a cocoon in the soil where it hibernates.
They are active during afternoon sunshine and as well at dusk and night when they come occasionally to light.
