Nepheloleuca complicata, the Swallow-tailed moth, is a moth in the Geometridae family.

The Swallow-tailed Moth (Ourapteryx sambucaria) is a moth of the family Geometridae.

Elders are used as food plants by the larvae of some Lepidoptera species including Brown-tail, Buff Ermine, Dot Moth, Emperor Moth, the Engrailed, Swallow-tailed Moth and the V-pug.

The leaves are eaten by the larvae of some species of Lepidoptera such as Angle Shades, Lesser Broad-bordered Yellow Underwing, Scalloped Hazel, Small Angle Shades, Small Dusty Wave (which feeds exclusively on ivy), Swallow-tailed Moth and Willow Beauty.

The one I'm currently stuck with is 'vliervlinder,' which I have found referred to as 'ourapteryx sambucaria.'
