Apotomis semifasciana, the short-barred grey marble, is a moth of the family Tortricidae. It was first described by the English entomologist Adrian Hardy Haworth in 1811.
The eggs are laid on willows ( Salix species). [1]
The larva is green; dorsal and subdorsal lines darker; head and plate of 2 yellowish-green. The larvae feed on the catkins and later the leaves of willows in May and June. [2]
The blackish brown pupa can be found in a silken cocoon, spun between two leaves of the foodpant in June and July. [2]
The wingspan is 17–20 mm. The head and thorax are grey. The forewings are grey, closely striated with whitish . The basal patch and a subtriangular central costal blotch are fuscous, black-marked, the apex of blotch truncate, marked with a black dash. The costa posteriorly is fuscous-spotted with a darker black-dotted subterminal mark in middle. The hindwings are grey, darker posteriorly. [3] Julius von Kennel provides a full description. [4]
Adults are on wing from July to August, flying from late evening onwards and coming to light and sugar. [1]. During the day they rest in foliage and are not usually easily disturbed. [2]
It is found in most of Europe, from Ireland to Russia. [5]
