ALNUS. Alder. [Betulaceae]

Alder (A. glutinosa) is the only native species of Alnus in Britain, although Italian Alder (A. cordata), Grey Alder (A. incana), Seaside Alder (A. maritima), Oriental Alder (A. orientalis), Red Alder (A. rubra) and Green Alder (A. viridis) have been introduced. Only one dipterous miner, the agromyzid Agromyza alnivora, is recorded on Alnus in Britain and elsewhere. The agromyzid Phytobia cambii feeds in the cambium of Salix and Populus in Britain and also Alnus, Betula and Carpinus elsewhere. Twenty-three non-dipterous miners are recorded on Alnus in Britain (see below). Elsewhere two additional non-dipterous British miner are recorded on Alnus (see below). A key to the European mines on Alnus is provided in Bladmineerders van Europa. This includes Heliozela resplendella, Leucoptera malifoliella, Atemelia torquatella, Paracrania chrysolepidella, Heterarthrus vagans, Scolioneura betuleti, Fenusa pumila, Fenusa dohrnii, Caloptilia elongella, Phyllonorycter stettinensis, Caloptilia falconipennella, Phyllonorycter rajella, Phyllonorycter vulturella, Phyllonorycter alnivorella, Phyllonorycter alpina, Phyllonorycter suaveolentis, Phyllonorycter strigulatella, Phyllonorycter kleemannella, Phyllonorycter froelichiella, Phyllonorycter chrysella, Anoplus plantaris, Anoplus roboris, Orchestes testaceus, Orchestes jota, Tachyerges pseudostigma, Tachyerges stigma, Ectoedemia minimella, Agromyza alnivora, Bucculatrix cidarella, Stigmella glutinosae, Stigmella alnetella, Apterona paludella, Coleophora siccifolia, Coleophora anatipennella, Coleophora serratella, Coleophora milvipennis, Coleophora alnifoliae, Coleophora limosipennella, Coleophora orbitella, Colephora binderella, Coleophora fuscocuprella, Coleophora violaceae, Coleophora ahenella and Incurvaria pectinea but not Bohemannia quadrimaculella or Bucculatrix thoracella.
