04.012 [B&F: 0102] Stigmella aceris (Frey, 1857)


Local in woodland, gardens and parkland from Kent to Hampshire. First recorded in our area from Teg Down, Winchester, in 1986, it was not found again until 2004 in the Fleet area, where the centre of population still lies. Perhaps under-recorded elsewhere, but the paucity of records from south Hampshire suggest it is genuinely rare elsewhere, and has not been recorded from the Isle of Wight to date. Wingspan 3.7-4.7 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 Field Maple, sometimes Norway Maple, over-wintering as a pupa. The mines are described in the following link:
