General Description

provided by University of Alberta Museums
"The adult is highly variable in wing pattern. Most commonly it is heavily mottled with brown to orange. The darkest markings are normally in the basal patch, slanted median band, and postmedian blotch that can extend to the anal angle. Distinctive bright yellow to cream squares are often present on the costa between the darker bands. The hindwings are typically dark grey with a lighter fringe. Males have a costal fold that extends to or barely past the basal patch. The larva is green with scattered pale warts and fine setae. The prothoracic shield is dirty green with variable amounts of black or dark brown laterally and the head is shiny dark or light brown. The larva can not be reliably separated from Choristoneura rosaceana and is closely similar to several other common tortricid species. (Chapman & Lienk 1971; Mackay 1962)"

Life Cycle

provided by University of Alberta Museums
The eggs are laid in oval batches of 20-100 eggs on the twigs or bark of the host tree. The first instar larvae often spin strands of silk and under ideal wind conditions can disperse to other areas. Larvae construct leaf-rolls where they emerge from to feed and when disturbed the larvae either retreat or suspend down on a line of silk. Populations are highly cyclical and can this species can become a pest in orchards. (Chapman & Lienk 1971; Razowski 1977; Kruse & Sperling 2001)

Trophic Strategy

provided by University of Alberta Museums
The larvae feed on the foliage and fruit of a wide variety of deciduous trees and shrubs and occasionally forbs. It can be a serious pest in apple, pear, cherry, plum, peach, apricot, and citrus orchards. (Chapman & Lienk 1971; Kruse & Sperling 2001; Razowski 1977; Freeman 1958; Forbes 1923)

Archips argyrospila

provided by wikipedia EN

Archips argyrospila, the fruit-tree leafroller moth, is a moth of the family Tortricidae. It is found in most of the United States and southern Canada.

The length of the forewings is 6-10.2 mm for males and 8.5-11.7 mm for females. Adults have a variable forewing colour consisting of combination of reddish brown, dark brown and tan. Adults are on wing from mid May to July in one generation per year.

The larvae feed on a wide range of plants and are considered a pest on apples and pears.[3] Recorded host plants include: Medicago, Malus, Prunus, Taxodium distichum, Phaseolus, Vaccinium, Betula, Acer negundo, Aesculus, Ceanothus, Cercocarpus, Citrus, Quercus, Eriodictyon, Vitis, Crataegus, Carya, Gleditsia triacanthos, Humulus, Syringa, Avena, Allium, Maclura pomifera, Pyrus, Rheum, Sassafras and Juglans species. First instar larvae bore into the buds of their host plant. Later instars roll or tie leaves together or tie them to fruit. They feed on the leaves, flowers, buds or fruits of the host plant. Pupation takes place within the larval shelter.[4]
