Plant Parasites of Europe

leafminers, galls and fungi

Lyonetia ledi

Lyonetia ledi Wocke, 1859


At first a narrow corridor, 20-40 mm long, with a central frass line, that runs along the leaf margin towards the tip. From there a blotch is made then; small leaves may be mined out completely. The larva makes a few slits in the side of the blotch away from the tip, through which most of the frass is ejected. Finally the larva leaves this mine, to make new blotches in one or two more leaves, that turn yellow like the first one. Mines invariably in the upper parts of the plant. Pupation outside the mine, in a cocoon that hangs freely in a sort of hammock fastened under a new leaf, that thereby is made to puff up.
