Leucoptera astragali Mey & Corley, 1999

Lepidoptera, Lyonetiidae

mine

The mine begins at a smooth, whitish, rather flat egg shell at the upperside of a leaflet, usually one per leaflet (but several for an entire leaf). From there a blotch is developed the in that the end occupies a large part of the leaflet. The mine is enlarged in a concentric pattern. There is much granular frass, that is glued to the upper epidermis and gives most of the central area of the mine a dark appearance. The full-grown larva makes a semicircular exit slit in the upper epiderm is, leaves the mine, and pupates within a cocoon.
