The forewing is light grey to pinkish grey with traces of thin dark lines. There are distinctive bands that are brown to grey and are edged by black lines. The hindwing is yellowish with fine darker grey reticulations. The larva is greyish green to cream coloured with a black head and thoracic shield (Duncan 2006).

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.
