Ennomos alniaria, the canary-shouldered thorn, is a moth of the family Geometridae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It can be found in Europe in a wide variety of biotopes where there are deciduous trees, perhaps mostly in deciduous forests and gardens.
Description[]
The wingspan is 34–42 mm. The length of the forewings is 16–20 mm. Resembles Ennomos quercinaria, but has a canary-yellow thorax. The forewings are scalloped and there are also two cross lines. The wings are ochre yellow with greyish flecks. The bands, a small discal spot on the forewing and a larger discal spot on the hindwing are grey. The larva is brownish-grey, long and thin, with four raised cross-bands on the dorsal side. It closely resembles a dead twig.[1]
Other Ennomos species are similar.
Distribution[]
Caucasus and Russia to western Europe. The northern limit is Fennoscandia and the southern limit is the northern Mediterranean.
Biology[]
The moths fly in one generation from July to October.[1] They are attracted to light.
The larvae feed on a number of deciduous trees including downy birch and silver birch, alder and goat willow.
