Agonopterix ocellana
(Fabricius) (
592-593
)
This widely distributed species is also associated with
willow (
Salix
). The larvae feed within spun leaves or
shoots, and sometimes cause slight damage to cultivated
plants. Adults (23 mm wingspan) are characterized by
the elongate, pale greyish-buff fore wings, each
suffused with black and marked with a prominent red
streak; they occur from August to April, hibernating
throughout the winter. The larvae (up to 20 mm long)
are green, with yellowish intersegmental divisions and
small, but distinct, black pinacula.
Carcina quercana
(Fabricius) (
594-595
)
A minor pest of deciduous ornamental trees and shrubs,
including beech (
Fagus sylvatica
), crab-apple (
Malus
),
flowering cherry (
Prunus
) and oak (
Quercus
). The
bright, apple-green, somewhat flattened larvae (up to
15 mm long) feed on the underside of leaves during
May and June, each sheltered beneath a slight web.
Pupation occurs beneath an opaque web from mid-June
onwards, and the bright yellow to greyish-pink adults
(15-20 mm wingspan) appear in July and August.
