Yorkshire Status: Local resident.

This is a recent colonist, being first found in Britain in Middlesex in 1996 and gradually spreading north. It was first recorded in Yorkshire in 2019. Initial records were from the east of VC63 and the south of VC61 but in 2024 it spread to the south of VC62. All of our records are of leaf mines on holm oak Quercus ilex. The mine is a strongly contorted gallery, almost entirely filled with black frass. There are often many mines in a leaf. The main confusion species is Stigmella suberivora which has not yet been recorded in the county.
