About Batrachedra praeangusta (Haworth, 1828)
Batrachedra praeangusta is a species of moth in the family Batrachedridae. It is native to Europe, and also found in North America. This moth was first described in 1828 by Adrian Haworth, based on a type specimen collected in England. The larvae of Batrachedra praeangusta feed on Populus species (poplars) and Salix species (willows), which are their foodplants. This species is distributed across both Europe and North America. Adult moths of this species have elongated narrow forewings, with a total wingspan measuring 14 to 15 mm. The forewings have a white base colour, patterned with a mixture of sooty black and paler markings. The hindwings are a shiny grey that becomes lighter toward the tip. Batrachedra praeangusta is univoltine, meaning it produces one generation per year. Adults fly from mid-June to early September; they can be found resting on tree trunks, and will come to light traps.
