Canary-shouldered Thorn Ennomos alniaria

Wingspan 38-42 mm.

Aptly named after the canary-yellow thorax, or 'shoulders', this is a fairly common species all over Britain.

It has a single generation which flies from July to October, and is regularly attracted to artificial light.

It frequents woodland, gardens and a range of other habitats, and the larvae feed on a variety of deciduous trees.
