Epinotia radicana
Red-striped Needleworm Moth
Epinotia radicana is a small tortricid moth known for its association with coniferous forests across northern North America. The species is recognized by its common name referencing the reddish larval stripes and needle-feeding habits. It has been documented from western Canada through to the northeastern United States, with a life cycle tightly synchronized to the phenology of its host trees. The species is not considered a significant forest pest despite its widespread occurrence in spruce-fir ecosystems.
Pityokteines
fir engraver beetles
Pityokteines is a genus of bark beetles (Scolytinae) known as fir engraver beetles. Species in this genus are significant pests of fir trees (Abies) and other conifers in the subfamily Abietoideae. Males initiate gallery construction and produce aggregation pheromones that regulate mass attack on host trees. The genus exhibits species-specific pheromone communication systems involving ipsenol and ipsdienol, which contribute to reproductive isolation among sympatric species.
Pityokteines ornatus
Pityokteines ornatus is a species of bark beetle in the family Curculionidae, subfamily Scolytinae. It was described by Wood in 1966. This species belongs to a genus of conifer-associated bark beetles that are significant forest pests in North America. The genus Pityokteines contains species that primarily infest fir trees (Abies spp.), with adults typically boring into the bark to create galleries where they lay eggs. The larvae develop within the phloem and cambium layers, potentially causing significant damage to host trees.
Pleroneura bruneicornis
Balsam Shootboring Sawfly
Pleroneura bruneicornis is a species of sawfly in the family Xyelidae, commonly known as the Balsam Shootboring Sawfly. The species is associated with Abies (fir) hosts, particularly balsam fir. It belongs to a primitive lineage of Hymenoptera characterized by distinctive larval feeding habits in conifer shoots. The species is rarely observed, with limited occurrence records.
Pseudohylesinus granulatus
Fir Root Bark Beetle
A bark beetle species in the weevil family Curculionidae, commonly known as the Fir Root Bark Beetle. Native to western North America, it is associated with fir trees and develops in root systems. The species was described by J.M. Swaine in 1918.
Semanotus
Semanotus is a genus of longhorn beetles (Cerambycidae) described by Étienne Mulsant in 1839. Species within this genus are primarily wood-boring pests of coniferous trees, with documented associations including juniper, fir, cedar, cryptomeria, and cypress. Several species cause significant economic damage to timber and ornamental plantings. The genus has a broad distribution spanning North America, Europe, Asia, and North Africa, with at least 19 recognized species.
Syneta simplex
Syneta simplex is a leaf beetle species native to North America. The species comprises two recognized subspecies with distinct elevational and host plant preferences. The nominate subspecies S. s. simplex occurs at lower elevations and feeds on Garry oak (Quercus garryana), while S. s. subalpina inhabits subalpine zones near timberline in Washington and British Columbia and feeds on alpine fir (Abies lasiocarpa). The species belongs to the family Chrysomelidae, a diverse group of herbivorous beetles commonly known as leaf beetles.
Zeiraphera unfortunana
Purple-striped Shootworm Moth, purplestriped shootworm
Zeiraphera unfortunana is a tortricid moth species native to boreal and subarctic regions of North America. The larvae are specialized feeders on coniferous trees, particularly spruce and fir species, where they develop in shoots and buds. The species was described by Powell in 1983 and is one of several Zeiraphera species known as 'budworms' or 'shootworms' due to their larval feeding habits.
