Phytomyza glechomae is a fly whose larvae mine the leaves of Ground-ivy (Glechoma hederacea). The mine has a short upper surface gallery, then winding to form a blotch; finally becoming linear again- the last section being shallow and looking green.
The mine is likely to occur anywhere that Ground-ivy grows.
The mines can be seen in late Spring and late Summer.
Widespread and probably fairly frequent in Britain, although under recorded.
Under recorded, but probably fairly frequent in Leicestershire and Rutland.
