Dotted border moth
Larvae of this generally common species frequently
occur on ornamental trees and shrubs, including alder
(
Alnus
), birch (
Betula
), crab-apple (
Malus
), hornbeam
(
Carpinus betulus
), oak (
Quercus
) and willow (
Salix
).
They feed on the foliage from April to late May or early
June and then pupate in the soil. Adults appear in the
following March or April. Larvae (up to 30 mm long)
are rather slender, olive-green to brownish, with pale
patches along the sides and, often, a series of blackish
x-shaped markings along the back. Adult males
(30-35 mm wingspan) are mainly yellowish brown, the
fore wings marked with dark crosslines and a
characteristic row of black dots along the outer margin.
Females (7-10 mm long) are greyish brown, mottled
with black; the wings are reduced to short stubs, the
hind wings being the longer pair.
