Species Details

ABH: 15.019

BF: 313

Family: Gracillariidae

Subfamily: Acrocercopinae

Taxon: Acrocercops brongniardella

Authority: (Fabricius, 1798)

Vernacular: Oak Cloud

Account: Local in open woodland, mainly south of a line from Lincolnshire to Herefordshire and Worcestershire, scarce elsewhere into Wales and Ireland (MBGBI Vol 2). Once rather scarce in Hampshire and on the Isle of Wight, this species has now been found widely throughout. Wingspan 8-10 mm. The second generation, when it occurs, overwinters to emerge in spring. Imago seldom encountered at light, and more likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of oak Quercus, including Evergreen Oak.

Accounts provided by and used with the kind permission of Mike Wall, Hampshire County Moth Recorder. These will in due course be gradually replaced with species accounts with a Surrey context.
