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.
