350 Phyllonorycter insignitella
(Zeller, 1846)Wingspan c. 7-8mm.
A rather rare and local species in Britain, having been found in a handful of scattered localities, including Northern Scotland, Western Ireland, Yorkshire/Durham and Kent.
The larvae feed on clover (Trifolium) and restharrow (Ononis), forming a blister mine on the underside of a leaf, causing it to pucker strongly.
Adult moths are on the wing in two generations: May and August.
