Archips rosana (Linnaeus) (Tortricidae: Tortricinae: Archipini)
Common names: rose tortrix, European leafroller
Synonyms: acerana (Tortrix), ameriana (Tortrix), avellana (Tortrix), hewittana (Cacoecia), laevigana (Tortrix), nebulana (Lozotaenia), obscura (ab.), ochracea (ab.), orientana (var.), oxyacanthana (Tortrix), splendana (var.), variana (Pyralis)
FWLFWL:
forewing length; the distance from the base of the forewing to the apex, including fringe
: 7.0-9.0 mm (male); 8.5-10.5 mm (female)
Forewings are light brown to brown with dark-brown markings that vary in expression. Hindwings are grayish brown with yellowish-orange apical shading. Males have a forewing costal foldforewing costal fold:
a flap or fold at the base of the forewing that contains specialized sex scales
.
Male genitalia are characterized by a slender, finger-like uncusuncus:
a sclerotized process which is fused to the posterodorsal margin of tergum IX
; absent sociisocii:
a pair of lightly sclerotized setose lobes
; and broad, subtriangular, membranous valvaevalva:
an appendage flanking the intromittent organ that is used to clasp the female during copulation
. Female genitalia are characterized by a long, narrow ductus bursaeductus bursae:
a membranous tube connecting the ostium bursae to the corpus bursae
with a cestumcestum:
a long, bandlike sclerotization of the wall of the ductus bursae
; and a moderate, daggar-like signumsignum:
a sclerotized projection or patch on the interior of the corpus bursae
in the corpus bursaecorpus bursae:
a dilated membranous sac at the anterior end of the bursa copulatrix
.
The following account is summarized from Swatschek (1958)Swatschek (1958):

Last instar larvae are 15-20 mm in length. The abdomen is dull pale green to dark olive green with pale pinaculapinaculum:
flattened sclerotized plates on a caterpillar that bear the setae
. The head is reddish brown to dark brown. The greenish-brown prothoracic shieldprothoracic shield:
a sclerotized plate on the dorsal surface of the prothorax
is shaded posteriorly with dark brown to black; the degree of shading varies. Thoracic legs are brown to black.
Some phenotypes of Archips rosana can appear similar to several other Archips species, including A. betulana, A. crataegana, A. grisea, A. oporana, A. podana, and A. xylosteana. Forewing markings in most A. rosana individuals are more subdued than in these other species.
Larvae of A. rosana are similar to those of Adoxophyes orana, Archips podana, and Choristoneura rosaceana.
The following account is summarized from Chapman & Lienk (1971).
Archips rosana completes one generation per year. Adults are present from late June to August.
The life cycle of A. rosana is similar to that of Archips argyrospila. Females lay eggs in masses of approximately 60 individual eggs on woody parts of the host plant. Eggs overwinter and larvae hatch the following spring. Larvae feed on leaves, flowers, and small fruits, rolling leaves in later instars. Pupation occurs in the final larval feeding site.
Archips rosana is a pest of fruit trees and other Rosaceae in Europe and the Pacific Northwest. Larvae are polyphagous, feeding on members of more than 15 plant families. Chapman & Lienk (1971) speculate that primary hosts are apple, currant, hawthorn, pear, and privet.
