 Taken at Aston, Oxon., on July 20th 2024. (© David Hastings) (1/60th sec at f1.6) DescriptionFamily: Geometridae (ABH : 70.218) Wing span: 22 - 30mm The normal form of this moth has dark crosslines and veins on the upper- and under-sides of both wings, creating a crisp network effect. There are subspecies that are dark brown, yellow, or white, with or without cross-bands. It is resident and common throughout most of the British Isles. It may also be an immigrant. It generally occurs on open ground, including gardens, and ranging from calcareous grassland, sand-dunes and fens to heath-land and moorland. In southern Britain there are probably two overlapping generations, May-June and July-September. It over-winters as a pupa underground. Larvae feed on clovers, trefoils and Lucerne. It often lands with its wings partially raised, like a butterfly. It is active by day, and is easily disturbed from vegetation. It comes to light.
