Stigmella rhamnella mines

Rhamnus saxatilis, Austria, Traunstein area; from Klimesch (1951b)

mine

Fairly long corridor, suddenly turning into an elongated, full depth blotch. The corridor may follow the precise leaf margin for a long distance. When this does not happen the corridor is laid in close loops, often more or less “intestine-like” in semicircles. In the first section of the corridor frass occupies almost all space, further up the frass line becomes somewhat narrower.

host plants

Rhamnaceae, oligophagous

Rhamnus alpina, cathartica, pumila, saxatilis.
