Classification

Family:Nepticulidae
Subfamily:Nepticulinae
Genus:Stigmella
Species:incognitella
Authority:(Herrich-Schäffer, 1855)

Local in woodland, gardens, orchards and parks throughout much of southern Britain. Recorded very infrequently in Hampshire and on the Isle of Wight, although perhaps more common than the records suggest. Wingspan 5-6 mm. Adults of this species and S. perpygmaeella are difficult to distinguish except by dissection of the genitalia; however, S. incognitella tends to be slightly larger, the forewing is darker and more obviously glossed with purple, the cilia are darker at the tips, and the hindwing is slightly darker, especially in the male (MBGBI Vol 1). Larva mines leaves of Apple, over-wintering as a pupa.

The abundance in each month is indicated as follows:
