Species Details

ABH: 15.004

BF: 282

Family: Gracillariidae

Subfamily: Gracillariinae

Taxon: Caloptilia elongella

Authority: (Linnaeus, 1761)

Vernacular: Alder Stilt

Account: Common wherever the foodplant occurs, throughout much of the British Isles, as far north as the Orkneys Overwinters as an adult, often in an evergreen such as Yew. The summer generation is relatively small and may not occur in unfavourable years. Similar in particular to C. betulicola, but also C. rufipennella and C. hemidactylella, and records require dissection for accurate determination. The larva feeds on Alder, at first mining the leaves and feeding initially on sap, later on the parenchyma; later it spins part of a leaf into a cone and lives and feeds therein.
