|scientific name Archepandemis coniferana |
Mid to late July in Alberta (Freeman 1965).
The forewing has a chequered appearance with the basal, median, and PM bands being block-like and dark grey with an irregular black border. The ground colour is white and is irregularly interrupted by fine black lines. The hindwing is evenly dark grey.
This species can be separated from the much more commonly collected Archips packardiana by the pattern of white markings on the forewing. In A. coniferana, the middle white costal spot is roughly continuous with the white band that extends down towards the anal angle, while in A. packardiana, these two markings are clearly disjunctive from each other. There are two other eastern boreal members of this genus that are equally rarely collected and should be looked for in Alberta. Archepandemis morrisana is smaller with a wingspan of under 16 mm, while in A. coniferana it is over 17.5 mm. Archepandemis borealis can only reliably be separated through genitalic characters (Mutuura 1978).
Unknown, rarely collected, all records are of reared individuals.
Larvae have been reared from Lodgepole Pine (Pinus contorta), Douglas Fir (Pseudotsuga menziesii), and Juniper (Juniperus sp.) in Alberta; Engelmann Spruce (Picea engelmannii) and Western Hemlock (Tsuga heterophylla) in British Columbia. There is also a doubtful record for cottonwood (Populus sp.). (Freeman 1965; Mutuura 1978)
Known from Willow Creek, Coleman, West Porcupine, Snaring River, and Athabasca in Alberta; also in British Columbia and California.
This species was taxonomically confused with and formed part of the paratype series for the eastern A. borealis by Freeman (1965)
