Ectoedemia septembrella leaf mine

The leaf mine of the Nepticulid moth Ectoedemia septembrella occurs on Hypericum species including Rose-of-Sharon (H. calycinum) and other ornamental species. It was first recorded in Glamorgan in Cardiff as recently as 2004 and is now well-established there. It was first found in Swansea in 2006 by Martin White in Swansea Marina and a thin scatter of subsequent records indicate that it is now probably widespread in urban situations around the city. The above photo was taken in Gorseinon today. Please report if you see this recent colonist...
