Adoxophyes orana (Fischer von Röslerstamm)
( 621-622 )
Summer fruit tortrix moth
This species is widely distributed in Europe and, since
the 1950s, following a noticeable westerly extension of
its range, has also become established as an important
fruit pest in south-eastern England. Although associated
mainly with fruit trees, the larvae also occur on various
other hosts, including alder ( Alnus ), birch ( Betula ),
hazel ( Corylus ), honeysuckle ( Lonicera ), poplar
( Populus ), rose ( Rosa ) and willow ( Salix ). They feed on
buds and also web the foliage of the young shoots, but
damage caused on ornamentals is unimportant. The
larvae (up to 20 mm long) are yellowish green or
greyish green to dark green, with small pale pinacula
and a yellowish-brown head and prothoracic plate. They
occur in two main broods, from June to August, and
from September to May. The greyish-brown adults
(15-22 mm wingspan) occur in June, with a larger flight
extending from mid-August to September or October.
Aleimma loeflingiana (Linnaeus) ( 623-624 )
This widely distributed and generally common
woodland species is associated mainly with oak
( Quercus ) but also attacks hornbeam ( Carpinus betulus )
and maple ( Acer ). The larvae feed within folded or
rolled leaves throughout May and usually pupate in
June. Attacks are sometimes noted on young cultivated
trees but are of no economic importance. The larvae (up
to 15 mm long) are green to blackish green, with
blackish-brown to black pinacula, head, prothoracic and
anal plates. Adults, which occur in June and July, are
mainly whitish brown to dark brown, with a dark
margin at the base of the cilia.
Ancylis mitterbacheriana (Denis &
Schiffermüller) ( 625-626 )
A locally common pest of beech ( Fagus sylvatica ) and
oak ( Quercus ). Eurasiatic. Widely distributed in Europe.
