In-Depth Information
DESCRIPTION
Adult:
12-16 mm wingspan; fore wings mainly
brownish orange to whitish, with a prominent reddish-
brown or chocolate-brown dorsal patch, and a curved
blackish streak towards the apex.
Larva:
up to 12 mm
long; greyish green to yellowish green, with pale and
relatively large pinacula; head yellowish brown to
greenish brown, marked with black; prothoracic plate
light green to yellowish brown, with a pair of blackish
lateral patches towards the hind margin and blackish
markings dorsally; anal plate light green, marked with
blackish brown.
Pupa:
6-8 mm long; light reddish
brown.
DAMAGE
Larval habitations attract attention when present on
nursery or specimen trees, but feeding damage is
superficial and of little or no importance.
Ancylis upupana
(Treitschke) (
627-628
)
A locally distributed species, associated mainly with
birch (
Betula
) but also attacking elm (
Ulmus
). Although
generally uncommon, the larvae are found,
occasionally, on nursery and specimen trees, sheltering
between spun leaves and causing minor damage to the
expanded foliage. They feed from July to September,
overwintering when fully fed and pupating in the spring.
Larvae (up to 12 mm long) are greenish grey to dark
olive-brown, with dark pinacula (those on the thoracic
segments being most prominent) and a black or
brownish head and prothoracic plate. Adults (12-18 mm
wingspan) are mainly brown, marked with silvery grey
and brownish orange; they occur in May and June.
LIFE HISTORY
Adults occur in May and June, and are most common in
or close to beech and oak woodlands. Larvae inhabit
individual pod-like shelters, formed out of a folded leaf,
and devour the innermost surface. They feed from July
to September, overwinter in the larval habitation and
pupate in the following spring.
