Pandemis heparana (Denis & Schiffermüller) (Tortricidae: Tortricinae: Archipini)

Common names: dark fruit-tree tortrix

Synonyms: cappana (Tortrix), cappata (Tortrix), carpiniana (Tortrix), fasciana (Pyralis), heperana (Tortrix), jamaicana (Teras), padana (Tortrix), pasquayana (Tortrix), rubrana (Tortrix), subclarana (var.), vulpisana (Lozotaenia )

Adult Recognition

FWL: 8.0-12.0 mm

Adults are medium brown with fasciatefasciate:
a wing pattern that is comprised primarily of transverse bands (fasciae)
markings and light to medium grayish-brown hindwings. Males lack a forewing costal foldforewing costal fold:
a flap or fold at the base of the forewing that contains specialized sex scales
and notched antennae.

Male genitalia are characterized by a broad, quadrate uncusuncus:
a sclerotized process which is fused to the posterodorsal margin of tergum IX
; rounded valvaevalvae:
plural of "valva"
; and a pistol-shaped phallusphallus:
the male intromittent organ (penis); see "aedeagus"
. Female genitalia are characterized by a 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
with a large basal plate.

Similar Species

Pandemis heparana can be separated from other Pandemis included on this site by the grayish-brown hindwings and the lack of dark scales on the second abdominal sternite in the male.

The following table lists a combination of wing color and geographic distribution that can be used to identify many Pandemis individuals collected in the U.S.

Species Forewing color Hindwing color Sex scales on male 2nd abd. segment Distribution

MacKay (1962a) examined several species of Nearctic Pandemis and could find no species-specific larval characters. Diagnostic characters for the genus include: SD2 on A1-8 on same pinaculumpinaculum:
singular of "pinacula"
as SD1; L1 and L2 anterioranterior:
before, to the front, toward the head
to spiracle on A2-8; SV group on A1,2,7,8,9 usually 3:3:3:2:2; D2s on A8 as far apart as D1s; D1 on A9 on its own pinaculumpinaculum:
singular of "pinacula"
; anal setae very long; anal combanal comb:
a toothed structure on the last abdominal segment used to eject frass away from the feeding larva; also termed "anal fork"
with 6-8 teeth.

Biology

The following account is summarized from Bradley et al. (1973).

In Europe, Pandemis heparana completes one or two generations per year. Adults are present June-July for the first generation and August-September for the second generation.

Females deposit eggs in masses on the upper surface of leaves. Larvae feed on leaves and construct a hibernaculum in the second or third instar in which to overwinter. Larvae resume feeding in the spring. Pupation occurs in the final larval feeding site.

Larvae of Pandemis heparana are polyphagous and have been recorded feeding on plants in more than 20 families. This species is considered an occasional orchard pest.

Distribution

Pandemis heparana is widely distributed in the Palearctic from Western Europe to Asia. In North America it has been introduced to the Pacific Northwest. The first North American records are from British Columbia in 1978 (Doğanlar & Bierne 1979). It is now also present in the northeastern U.S. and eastern Canada.
