scientific name    Argyrotaenia quadrifasciana    

common name     Lesser All-green Leafroller, Four-lined Leafroller

Moderately common in the aspen parkland, especially where cherry shrubs are common.

Early July to late August in Alberta, starting in late June elsewhere (Chapman & Lienk 1971).

The forewing is bright orange with abundant fine yellow reticulation throughout. In females there is variably expressed thin slanted bands lacking reticulation in the antemedian, postmedian, and apical corner, in males these markings are dark purple. The hindwing is white to light orange in the femal and dark greyish in the male. In the similar Sparganothis reticulatana the forewing is yellow with variable orange reticulation and there is a thin perpendicular line partially or completely connecting the antemedian and postmedian lines. As the common name suggests, the larva is completely green except for a small black spot amongst the eyes and is closely similar to A. velutinana. (Chapman & Lienk 1971)

life history
Eggs are laid on the upper surfaces of leaves in dull greyish yellow masses of about 50 eggs each. Larvae hibernate in a hibernaculum in the thrid instar and resume feeding on the buds in early spring. Later instars produce copious webbing on terminal shoots and rarely stray from it. Pupation occurs on the shelter and lasts up to two weeks. (Chapman & Lienk 1971)

Not of concern.

diet info
Hawthorns (Crataegus spp.), serviceberries (Amelanchier spp.), cherries (Prunus spp.), and apples (Malus spp.) are the main hosts of the larva (MacKay 1962).

From Alberta to Nova Scotia, south to New Jersey, Nebraska, and North Dakota. In Alberta known mostly from the aspen parkland.
