***Euchoeca*** is a [monotypic](/source/Monotypic) moth genus in the family [Geometridae](/source/Geometridae) erected by [Jacob Hübner](/source/Jacob_H%C3%BCbner) in 1823. Its only species, ***Euchoeca nebulata***, the **dingy shell**, was described by [Giovanni Antonio Scopoli](/source/Giovanni_Antonio_Scopoli) in 1763. It is found in the [Palearctic realm](/source/Palearctic_realm), from Europe across [Russia](/source/Russia) to [Japan](/source/Japan).[3]

The [wingspan](/source/Wingspan) is 23–25 millimetres (0.91–0.98 in). The ground colour of the forewing is sandy brown or orange cream. The wings have very fine and faint darker cross lines and creamy-brown chequered fringes. There is a double curve on the [termen of the hindwing](/source/External_morphology_of_Lepidoptera). The caterpillar is green, with three lines along the dorsum, the central one dark green, and the others yellow and a purple stripe runs along under the spiracles. In another form the general colour is greyish with a reddish-brown stripe along the back, and series of spots of the same colour along the sides.[4]

The moth flies from April to September depending on the location.

The larvae feed on [birch](/source/Birch) and [alder](/source/Alder) in damp woodland, fens and other marshy areas.
