Argyresthia goedartella (Linnaeus, 1758)

golden argent

on Alnus, Betula

gall

The larva lives from autumn till spring as a borer in a male catkin. The catkin becomes somewhat distorted; it has an opening at the side, through which frass is ejected. Pupation external.

host plants

Betulaceae, oligophagous

Alnus glutinosa; Betula pendula, pubescens.

That they live also in the catkins of Quercus, as is stated by, among others, Baldizzone (2008a), does not seem probably, given the very different structure of oak male catkins.

larva, pupa

described by Patočka (1998a), Patočka & Turcáni (2005); see also Schmid.
