The Lesser Yellow Underwing (Noctua comes) is a moth
of the family Noctuidae
. It is found throughout Europe
. It was introduced into British Columbia
in about 1982 and has spread southward in the Pacific Northwest. It has recently been reported from Ontario
(Crolla 2008). Full synonymy given in Lafontaine. It is a common species but not as abundant as its larger relative Large Yellow Underwing
.
This species generally has the appearance of a "scaled-down" (wingspan
38-48 mm) version of the Large Yellow Underwing. The forewings are equally variable, from light brown to almost black and it also has orange-yellow hindwings with a black sub-terminal band. The hindwings also have a black discal spot, usually absent from the larger species. It flies at night from July to September and is attracted to light and flower
