Quite often a pest of cultivated and garden peas and various related Leguminosae, the larvae of this moth feed internally in the pods, eating away the peas themselves.

Its distribution ranges over much of mainland Britain, more plentifully in the south, and locally in Ireland. In the Butterfly Conservation’s Microlepidoptera Report 2011 this species was classified as common.

It appears to be uncommon in Leicestershire and Rutland, where there are few records. L&R Moth Group status = D (rare or rarely recorded).
