Epinotia nemorivaga (Tengström, 1848)
Arctostaphylos uva-ursi, France, Mont Ventoux, leg MJ Gijswijt
The larve begins by making a corridor that generally traverses the leaf perpendicularly, and later remains visible as a brown ridge. Upon arrival at the other side this corridor is vacated through an untidy hole (In some instances an exuvium was found here). Next the larva makes a a large, untidy full depth blotch, either in the same leaf or in a neighbouring one. The blotch, that may occupy the entire leaf, contains many coarse, oval, frass grains. The larva leaves the blotch through a large circular opening. Before moving to a new leaf to old and the new are connected with silk.
