Leucoptera cytisiphagella

Description

Leucoptera cytisiphagella is a moth in the family Lyonetiidae. It is found in Hungary and Bulgaria. The larvae feed on Chamaecytisus austriacus. They mine the leaves of their host plant. The mine starts as a very narrow gallery descending along the leaf margin until about halfway down. Then the corridor widens into a blotch that eventually becomes full depth and occupies the entire leaflet. The frass is deposited in a central accumulation. Pupation takes place outside of the mine.
