Stigmella pretiosa mine

Geum rivale, Austria, 1200 m; from Klimesch (1981a)


Egg usually at the upperside of the leaf. The mine is a long, strongly vein-determined corridor. In the first part the frass lies in a rather narrow, often interrupted central line; further on the frass line is broader and more diffuse. Frequently more than one mine in a leaf.

host plants

Rosaceae, oligophagous

Geum montanum, rivale, urbanum; Rubus caesius, fruticosus, idaeus, macrophyllus.


One generation; active larvae generally from mid September to mid October. In Poland, Germany and Austria all, or at least most, larvae hibernate in the mine; in Scandinavia the larvae leave the mine before winter (Johansson ao, 990a).


Not known from the Benelux countries (Fauna Europaea, 2009).
