Key to extant species of British Scrobipalpa
I have found this genus to be one of the most confusing of the British Lepidopteran fauna. Most are variable. S.costella is the only common species that can be readily and reliably identified without recourse to genital dissection (it has a large dark blotch on the costa of the forewing). S.murinella is the smallest of the genus and its size (ws9-10mm) hardly overlaps with any other. It is rare and has only been found on Rum, Coll and near Braemar. S.clintoni has only been found on the West coast of Scotland. This leaves 10 species for the lepidopterist in England to choose from.
