Species Account

Most records are of leaf-mines.

Sutton & Beaumont, 1989: Thinly distributed in vice-counties 62 to 65, not recorded from VC61.

Argus 66, 2012:
VC61. Barlby, mines on hazel 13.9.2012 (CHF). NEW VICE-COUNTY RECORD.

2013 (CHF): Widespread across the county wherever hazel grows but scarcer in VC61. This is the less common of the two Stigmella species mining hazel leaves and must be separated from the much commoner Stigmella microtheriella. This can be difficult in old mines and it is much easier when they are fresh. The most important feature is the early part of the mine which is almost filled with frass whereas in microtheriella the early frass line is thin leaving clear margins. The mine is not angular and is independent of the leaf venation compared with microtheriella where the mine often follows the veins. This species also feeds on hornbeam.
