Epiblema cynosbatella
(Linnaeus) (
658
)
A common species on wild and cultivated rose (
Rosa
).
In mainland Europe various other plants, including
ornamentals such as
Chaenomeles
, are also attacked.
Widespread in Europe.
Epiblema rosaecolana
(Doubleday) (
661-662
)
Frequently a pest of cultivated species of rose (
Rosa
)
but associated mainly with sweet briar (
R. rubiginosa
).
Eurasiatic; also established as an introduced pest in
North America. Widely distributed in Europe.
DESCRIPTION
Adult female:
16-22 mm wingspan; fore wings creamy
white, marked with brownish black, bluish grey and
light brown, and with a large blackish basal patch; hind
wings dark grey; labial palps yellow.
Adult male:
similar to female but hind wings light grey.
Larva:
up
to 18 mm long; reddish brown, with inconspicuous
pinacula.
Pupa:
9-11 mm long; blackish green.

LIFE HISTORY
Larvae attack the young shoots and flower buds of rose
bushes, feeding mainly in April and May. They then
pupate in the larval habitation, usually between two spun
leaves or in a spun shoot. Adults occur in May and June.
DAMAGE
Damage to foliage is of little consequence, but infested
shoots are distorted and flower buds destroyed.

LIFE HISTORY
Adults occur from late June to August, and are often
abundant in the vicinity of rose bushes. Eggs are
deposited on the bushes, but do not hatch until the
following spring. Larvae feed throughout May and early
June, each sheltering in a tightly spun shoot and
devouring the innermost tissue. Pupation usually occurs
in the larval habitation.
DAMAGE
Infested bushes are disfigured and new shoots distorted
or destroyed. The larvae also damage flower buds.
