Common in hedgerows and scrubland throughout much of the British Isles, except for Scotland. In Hampshire and on the Isle of Wight common wherever there is Blackthorn, principally along the coast, and on the chalk. Wingspan 4-5 mm. Imago can only be separated from similar Stigmella species by dissection of the genitalia, and more frequently recorded in the larval stage, when the distinctive mines in the leaves of Prunus sp., especially Blackthorn, can be easy to spot where present.
