Argyresthia goedartella, the bronze alder moth, is a species of moth of the family Argyresthiidae.
This very common species can be found in most of Europe and in North America. [2] [3] [4] [5]
Argyresthia goedartella has a wingspan of 10–13 mm. [6] [7] These tiny moths have pale ochreous head with white antennae and white forewings with coppery-golden markings. A characteristic coppery-golden Y-shaped marking is present in the middle of the wings. [6] Hindwings are dark gray. Abdomen is grayish fuscous, while legs are brownish white. [7] [8]
It is a univoltine species. These moths fly from May to October. They fly at night and on sunny afternoons and mainly feed on the nectar of tansy ( Tanacetum vulgare ). [6] The larvae feed on birch (Betula species) and alder ( Alnus glutinosa ). [3] They overwinter in a shoot or hard male catkin of the host plants. In late March or April, larvae congregate and pupate in a cocoon under the bark. [6] [7]
