This time last month I found my first leafmines on Ground-ivy (Glechoma hederacea) (and blogged about them on 14 November, Leafmines: Coleophora albitarsella). Now, I’ve found another new-to-me leafmine on this same plant species only this one was made not by the larva of a moth but rather but the larva of a fly called Phytomyza glechomae. The mines are quite distinctive, starting with a winding gallery and finishing with a wider blotch, with plenty of frass scattered throughout. As always, you can read more and see plenty of images on the excellent British Leafminers website.
