Pandemis dumetana

Author: (Treitschke, 1835)

Strawberry tortricid

Species Overview:

Adult: 18-22 mm wingspan; forewing ground colour dull brown strigulated with dark grey-brown, marking dark grey-brown, veins lined with dark grey-brown forming a reticulate pattern; hindwing white; anal part of wing suffused with grey. Antennae of male without a basal notch.
Egg: deposited in batches of various sizes on the underside of leaves of the food plant.
Larva: slender; head green with region of stemmata and posterior margin blackish; prothoracic and anal plates green; abdomen green, with paler sub-dorsal lines, sometimes with a dark green dorsal line; pinacula green.
Pupa: 9-13 mm; light brown to blackish brown; dorsal parts of cremaster deeply depressed in basal half, apical half longitudinally wrinkled; bristles on cremaster hardly curved, except hooked apices; in the larval habitation.

Taxonomic Description:


Pandemis dumetana male 1
Pandemis dumetana male 2
External characters: Antennae weakly dentate-ciliate, without notch near base; scape dull brown, flagellum light brown posteriorly with indistinct dark segmental bars. Frons, vertex and labial palpus dull brown, palpus paler interiorly. Forewing slightly expanding posteriorly; costa strongly curved basally, hardly concave subapically; apex short; termen hardly sinuate, not oblique. Forewing ground colour characteristically dull brown strigulated with dark grey-brown, veins lined with dark grey-brown forming a reticulate pattern; marking dark grey-brown, margins of basal and median fascia well defined, edged with dark brown; usually a distinct dark stria from triangular pre-apical spot to tornal area. Hindwing white, weakly strigulated apically; anal part of wing suffused with grey (Bradley et al., 1973).

female gen. P. dumetana
Genitalia: Sterigma weak, anterior (cup-shaped) part long; antrum distinctly elongate, tubular, with parallel sclerites. Ductus bursae without cestum. No sclerites are present in the corpus bursae except for capitate signum.


In Western Europe, moths fly in July and August. They fly freely from sunset onwards. Eggs are deposited in batches of various sizes on the underside of leaves of the food-plants. The incubation period lasts 7-10 days. Larvae feed for a short period of time. Second instar larvae construct a silken hibernaculum in the fold of a leaf, and hibernate until the following spring. Larvae live within rolled leaves and occasionally flowerheads. Pupation occurs in the larval habitation, in June and July. Development lasts 8-10 days (Bradley et al., 1973; Bovey, 1966).
In Korea, moths were collected between late June and early September (Byun et al., 1998).

Host plants:

Apple (Malus), pear (Pyrus), peach (Prunus), strawberry (Fragaria), Centaurea, Cicium, Hedera, Lysimachia, Lathyrus palustris, Medicago sativa, Mentha, Petasites japonicus, Phaseolus sp., Quercus, Rubus, Thalictrum, Trifolium repens, Urtica.


Pandemis dumetana is a pest of apple, pear, peach and strawberry. Larvae feed on leaves and blossoms.


Throughout Europe and the Middle East to Siberia, Korea and Japan.
