Synonyms and other taxonomic changes
Choristoneura Lederer, 1859. Taxonomic notes:
According to ITIS, four North American species formerly placed in Choristoneura are now placed in the genus Archips. These are:
Archips fractivittana (Broken-banded Leafroller)
Archips fumiferana (Spruce Budworm)
Archips pinus (Jack Pine Budworm)
According to All-Leps and almost every other source (based on Internet searches), these species are still in the genus Choristoneura, so they're being left here for now.
The Species 2000 & ITIS Catalogue of Life, 3rd January 2011, places these species in Choristoneura while continues to place them in Archips.
Nearctica (1) lists 17 North American species, 4 of which are considered by ITIS to be species of Archips, namely: fractivittana, fumiferana, lambertiana, and pinus. See Synonyms section above.
Pohl, et al. (2016) list 18 species.(2) One species in the checklist (biennis) has since been sunk into synonymy with another (freemani) by Brunet et al. (2016). This guide should be used only as a first step in identification. The first five species here (obsoletana, fractivittana, parallela, zapulata, and rosaceana) are often confused and not always separable. Refer to the rosaceana species page for a detailed explanation. Additonally, western specimens of the fumiferana group are generally impossible to identify from photos and present continued taxonomic difficulty. Only the two species which range into eastern North America (fumiferana and pinus) are included here; several other species occur in the west, and the fumiferana group taxon page should be consulted for further information.
