Phyllonorycter insignitella

Description

Phyllonorycter insignitella is a moth of the family Gracillariidae. It is found in all of Europe, except the Balkan Peninsula. The wingspan is 7–8 mm. The larvae feed on Lathyrus, Medicago lupulina, Ononis repens, Trifolium alpestre, Trifolium medium, Trifolium montanum, Trifolium pratense and Vicia species. They mine the leaves of their host plant. They create a lower surface tentiform mine that occupies only part of a leaflet. In full-grown leaves, the mine is strongly inflated and is largely hidden by the leaf.
