Cranberry tortricid

Species Overview:

Adult summer generation: 15-20 mm wingspan; head and thorax yellowish-orange or dark yellow; forewings yellowish orange, strigulated with orange or brownish; hindwings pale ochreous-grey.
Adult autumn generation: 15-20 mm wingspan; head purplish or brownish, also very pale; thorax brownish or greyish; forewings very variable, reddish-brown or violet-brown, with a broad whitish stripe along the costal margin, or monochromatic brown or blackish-brown with silvery-grey granulation; other forms have whitish forewings, the markings being brown or rust. Hindwings pale brownish-grey.
Larva: head brown, prothoracic plate greenish or head and prothoracic plate black-brown; thoracic legs dark brown; abdomen light to dark-green, pinacula concolorous.
Pupa: 8.5-10.5 x 2.3-2.6 mm; dark reddish brown.

Taxonomic Description:


Acleris fimbriana adults
A. fimbriana summer gen.
A. fimbriana autumn gen.
External characters: 15-20 mm wingspan; forewing expanding terminally; costa curved basally, then straight or slightly arced outwards; apex rounded, short; termen delicately convex.
* Summer generation adult: Head, thorax and labial palpus yellowish-orange. Forewing ground colour yellowish orange, strigulated with orange or brownish; cilia concolorous with ground colour; hindwings pale ochreous-grey.
* Autumn generation adult: Labial palpus purple-brown, somewhat sprinkled with brown and grey; head concolorous with palpi, frons sometimes rusty; thorax brownish. Forewing ground colour reddish-brown or violet-brown, with a broad whitish stripe along the costal margin, strigulated with darker brown; hindwings pale brownish-grey. Monochromatic brown specimens and blackish-brown specimens with silvery-grey granulation also occur. Other forms have pale coloured heads and thorax, and the ground colour of the forewing is whitish, the markings being brown or rust (after Razowski, 1984).

male gen. A. fimbriana
Genitalia: Tegumen small with rather narrow terminal lobes; socii very long, sparsely bristled terminally; tuba analis delicate, membranous posteriorly. Valva broad, costa strong; sacculus broad basally, concave before middle of ventral edge, then straight, curved upwards in terminal (sparsely spined) portion; brachiola very broad, large. Aedeagus strong, curved; 5 short but strong cornuti and large plate-shape sclerite present in vesica.


External characters: similar to male.

female gen. A. fimbriana
Genitalia: Sterigma proportionally small with rather short, pointed apically anterior projections; antrum heavily sclerotized, uniformly broad throughout, long, ductus bursae long, broad, thin before corpus bursae; signum rounded, dentate.


Adults of the first generation show minor variation in the intensity of the median fasciae; adults of the second generation are very variable. The ground colour varies from reddish-brown or violet-brown to dark brown; the whitish costal streak can be strigulated with black or can cover most of the wing, leaving a dark median fascia and some irregular spots. Furthermore, the markings can be atrophied.


The larvae of the first generation live in May and pupate by the end of the same month. Moths emerge in mid June. The larvae of the second generation appear in August and September. Moths of this generation fly until winter and then hibernate till spring.

Host plants:

Ericaceae, Vacciniaceae such as billberry, bog whortleberry, cranberry (Vaccinium), and Rosaceae such as sour cherry, sweet cherry, peach, apricot, almond (Prunus) and apple (Malus).


Larvae feed within rolled leaves at apices of the branches of the host plant.
Recorded as one of the three most injurious species on apple in Northern China (Ko-hsuin, 1974).


Palaearctic Region from Central Europe to China and Korea.
Acleris fimbriana minuta Rob. occurs in North America.


Pheromone unknown.
