Sutton & Beaumont, 1989: Widely distributed and common in vice-counties 62 and 63. Also recorded from VC64 but not from either VC61 or VC65.
2013 (CHF): Local in the south of the county. Adults can found flying round the lower branches of oaks in the daytime and rarely stray far from their foodplant. The larva makes a gall in the petiole or midrib then moves a short distance into the blade where it forms an oval cutout measuring from 4 x 2mm to 5 x 3mm, usually but not always at the base of the leaf.
