Life Cycle
provided by University of Alberta Museums
Archips alberta is a solitary defoliator that can cause some cone crop damage. The larva overwinters in the first instar and in the spring resumes mining needles and webs adjacent needles together. Later instars feed on foliage and cones, often with considerable webbing where it often later pupates in June. Adults frequent lights and eggs are typically laid in the dense crowns of Black Spruce.

Trophic Strategy

The larva mainly feeds on Black Spruce (Picea mariana), but also White Spruce (Picea glauca) and Engelmann Spruce (Picea engelmannii) foliage and cones (Freeman 1958; MacKay 1962; Razowski 1977; Duncan 2006).

Archips alberta is a species of moth of the family Tortricidae first described by James Halliday McDunnough in 1923.[1] It is found in North America, where it has been recorded across boreal Canada, south through the mountains to Utah. The habitat consists of coniferous forests.
The wingspan is 22–25 mm.[2] The forewings are light grey to pinkish grey with thin dark lines and brown to grey bands that are edged by black lines. The hindwings are yellowish with darker grey reticulations. Adults are on wing from early July to mid-August.
The larvae feed on Picea mariana, Picea glauca and Picea engelmannii. Young larvae mine needles and web adjacent needles together. Older larvae feed on foliage and cones. The larvae are greyish green to cream with a black head. The species overwinters as a first instar larva. Pupation takes place in a web.[3]
