Taxon: Ectoedemia subbimaculella

Authority: (Haworth, 1828)

Vernacular: Broken-barred Oak Dot

Account: Common and the most numerous of the three oak-mining Nepticulidae found in woodland, gardens and parkland throughout much of south-eastern England, north to Yorkshire Imago distinguished from most other Ectoedemia species by the white basal spot on the forewing (MBGBI Vol 1). Adults difficult to distinguish from other Ectoedemia species, and more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Sessile and Pedunculate Oak, often in fallen leaves, over-wintering as a pupa. The mines are described in the following link:
