Argyresthia goedartella, the bronze alder moth, is a species of moth of the family Argyresthiidae. DistributionThis very common species can be found in most of Europe and in North America.[2][3][4][5] Description 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]  BiologyIt is a univoltine species. These moths fly from May to October.[1] 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] References
