Common alder midget

<em>Phyllonorycter rajella</em>, commonly known as the Common Alder Midget, is a small moth in the family Gracillariidae. This species is assessed as Least Concern on the IUCN Red List and is distributed across Europe, with records from countries including Germany, the United Kingdom, and several Scandinavian nations. As its common name suggests, the larval stage of this moth is closely associated with alder trees (Alnus species), within whose leaves the caterpillars create characteristic leaf mines. Adult moths are small with intricately patterned wings typical of gracillariid moths, often featuring metallic or golden markings. The species typically completes one or more generations per year, with adults emerging in spring and summer. Leaf-mining activity by the larvae produces distinctive blotch or tentiform mines visible on the undersides of alder leaves. The Common Alder Midget is generally considered a specialist of riparian and wetland habitats where alder trees commonly grow. Biological traits of this species remain poorly documented in the scientific literature.
