Larva of broad-barred button moth (
Acleris laterana
).
Acleris emargana
(Fabricius) (
617-618
)
A generally common species, associated with birch
(
Betula
), poplar (
Populus
), pussy willow (
Salix caprea
)
and other broad-leaved willows. Minor infestations are
sometimes noted on nursery trees. The mainly green
larvae (up to 15 mm long) feed within folded leaves or
spun shoots during May and June. Damage also occurs
on alder (
Alnus
) and hazel (
Corylus
). Adults (16-22 mm
wingspan) are mainly brown, with a characteristic
emargination on the costa of each fore wing. They
appear from July onwards.

syn.
A. latifasciana
(Haworth)
Broad-barred button moth
This widely distributed and generally common species
is a minor pest of rose (
Rosa
) and certain other trees and
shrubs, but is more common on raspberry. The larvae
(up to 15 mm long) are whitish green, with a pale
yellowish-brown head; they feed between spun leaves
in May and June, causing conspicuous but usually
minor damage. The adults (15-20 mm wingspan) are
mainly whitish to ochreous, marked with black, brown
or red; they fly in August and September, and are often
common in gardens.
