Euchoeca is a monotypic moth genus in the family Geometridae erected by Jacob Hübner in 1823. Its only species, Euchoeca nebulata, the dingy shell, was described by Giovanni Antonio Scopoli in 1763. It is found in the Palearctic realm, from Europe across Russia to Japan. [3] The wingspan is 23–25 millimetres (0.91–0.98 in).

Occupying damp woodland, fens and other marshy areas, this ochreous-yellow moth is fairly commonly distributed in England and Wales, but is rare in Scotland. It is not known to occur in Ireland. The adult moths are on the wing in June and July, in a single brood. The larvae feed on the leaves of Alder (Alnus glutinosa).

Euchoeca nebulata, the dingy shell, is a moth of the family Geometridae. It was described by Scopoli in 1763. It is found in the Palearctic ecozone, from Europe across Russia to Japan.

Wingspan 23 to 25 mm. This is an ochreous-yellow moth. Occupying damp woodland, fens and other marshy areas. The adult moths are on the wing in June and July, in a single brood. The larvae feed on the leaves of Alder. This moth is fairly commonly distributed in England and Wales, but is rare in Scotland. It is not known to occur in Ireland.

This is a somewhat rare and local species, never found in large numbers even where it does occur. The moth was recorded from the edge of South Burn Wood on Waldridge Fell in 1951 (TCD), but when this was mentioned to the late Professor J. W. H. Harrison, it turned out that he had known it there for many years previously without telling anyone.

Widespread and common in Hampshire, but scarce on the Isle of Wight, with only one record so far this century. Wingspan 23-25 mm. Always rests with wings closed, when appears remarkably similar to Rannoch Looper Itame brunneata, with which there is no overlap of range in Britain. Larva feeds on Alder, over-wintering as a pupa.

Euchoeca nebulata (Dingy Shell) §2 male ID : Rests with wings closed (upper surfaces of forewings pressed together, like a butterfly); chequered fringes. Similar to Hydrelia flammeolaria (Small Yellow Wave) which rests with wings open and has simple fringes.

Dingy Shell always rests with its wings closed, which should separate it from Small Yellow Wave. Recording method. Easily disturbed by day, comes to light in small numbers. Life cycle. One generation. Overwinters as a pupa. Larvae late June to August, pupation taking place on the ground among plant debris. Larval foodplants

Status Damp woodland, fens and other marshy areas, often near water courses. Characteristic resting posture with wings closed. Easily disturbed by day from near food plant.
