Distribution in Great Britain and Ireland: Widespread in Britain, including Denbighshire (Cefn-y-bedd), London (Hampstead), Somerset (Cheddar), Derby (Miller's Dale) (Spencer, 1972: 57) and Warwickshire (Keresley) (Robbins, 1991: 123); North Somerset and South Wiltshire (NBN Gateway - N.B. includes Watsonian Vice Counties having publicly available records that fall within or overlap the vice county border at 10km resolution or better i.e. a record for a vice county may relate to an adjacent vice county - for included datasets see NBN Grid map below).

Leaf mines probably referable to this species also seen at Kent (Dungeness) (Spencer, 1972: 57).
