Mottled beauty moth
An often common but minor pest of trees and shrubs,
including birch (
Betula
), elm (
Ulmus
), hawthorn
(
Crataegus

following spring. Specimens are sometimes found on
ornamental trees in parks, gardens and nurseries but
they cause only slight damage. The greyish-white to
dark yellowish-grey adults (40-44 mm wingspan) occur
from June to July. In some seasons, there may be a
partial second generation.
