04.040 [B&F: 0074] Stigmella assimilella (Zeller, 1848)

 

Local in woodland throughout much of south-eastern England and in the Scottish Highlands. Probably under-recorded in Hampshire, where the extent of known records correlate with those areas in which the recording effort is concentrated. Not recorded from the Isle of Wight since 1973. Wingspan 5.4-6.2 mm. Adults difficult to distinguish from other Stigmella species, and more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Aspen, over-wintering as a pupa.
