Notes: Initially mines the stem or cladode. After two weeks it bores into the shoot tip and vacates this after two weeks. The larva then completes its feeding in a red or green berry, initially mining beneath the pericarp before boring into the interior. Infested fruits are bicolored red and green (as shown, with pericarp mined). In September -October the larva pupates within a cocoon on a lower cldode or stem. A rare moth found mostly in Dorset and Hampshire.
