Norfolk status Widespread in southern Britain, but it is subject to huge fluctuations in numbers.
The distinctive larva feeds on bindweeds (Calystegia and Convolvulus spp.) and Morning glory (Ipomoea) in July- August and in September. At first it makes a narrow gallery lined with frass, but subsequently it makes a series of large translucent yellowish brown blotch mines from which all frass is ejected. It also constructs under the leaf an 'aerial' network of silk threads in which it moves around and rests clear of the leaf surface when not feeding.UKmoths
