Leucoptera genistae is a moth in the family Lyonetiidae. It is found in France, Italy, Austria, Hungary and Bulgaria.[1]
The larvae feed on Genista anglica and Genista germanica. They mine the leaves of their host plant. The mines are undistinguishable from those of Leucoptera laburnella The mine starts as a densely contorted corridor, that quickly turns brown. It is followed by a more or less straight corridor entirely filled with greyish-green frass. Then it widens into a round blotch that overruns the earlier corridor and in the end may occupy half of a leaflet. Pupation takes place outside of the mine.[2]
