Arge cerulea
Arge cerulea is a species of sawfly in the family Argidae. Members of the genus Arge are commonly known as birch sawflies or rose sawflies, though specific common names for A. cerulea are not well documented. The species is characterized by its blue or cerulean coloration, as indicated by its specific epithet. Sawflies in this family are herbivorous, with larvae typically feeding on various woody plants. Adults are often found on flowers or foliage of host plants.
Banasa subcarnea
Banasa subcarnea is a species of stink bug in the family Pentatomidae, native to North America. It belongs to a genus of eleven species in North America, several of which are visually similar and require microscopic examination for reliable identification. Like other Banasa species, it is associated with woody plants and is not considered an agricultural pest.
Campaea perlata
Pale Beauty, Fringed Looper, Light Emerald
Campaea perlata is a medium-sized geometrid moth found throughout North America, commonly known as the pale beauty. Adults are pale greenish to white with faint continuous lines across both forewings and hindwings, with females notably larger than males. The caterpillar, called the fringed looper, is an inchworm with distinctive fringe-like setae and twig-mimicking camouflage. The species has two annual generations in most of its range, with larvae overwintering on exposed tree trunks and branches.
Dorytomus frostii
Frost's Aspen Weevil
Dorytomus frostii is a true weevil in the family Curculionidae, commonly known as Frost's Aspen Weevil. The species was described in 1916 and occurs in western Canada and potentially broader North American ranges. Like other members of the genus Dorytomus, it is associated with woody plants.
Erythroneurini
Erythroneurini is a diverse tribe of leafhoppers in the subfamily Typhlocybinae, comprising over 180 genera. The tribe has been extensively studied in the New World and southwestern China, with major taxonomic revisions published for genera including Erythroneura, Erasmoneura, Zyginama, Eratoneura, and Erythridula. Species within this tribe exhibit complex synonymies and are associated with woody deciduous vegetation.
Heliria
Heliria is a genus of treehoppers in the family Membracidae, established by Stål in 1867. The genus contains thirteen described species distributed in North America. Members of this genus are phytophagous insects associated with woody host plants. At least one species, Heliria praealta, has been documented feeding on chokecherry (Prunus virginiana).
Neolecanium
Neolecanium is a genus of soft scale insects (family Coccidae) established by Parrott in 1901. The genus includes species that are pests of woody plants, notably magnolia scale (Neolecanium cornuparvum), which is monitored by the USA National Phenology Network for phenology-based pest management. Like other soft scales, members of this genus possess a waxy protective covering and feed on plant phloem. The genus is included in the Pheno Forecast program, which uses heat accumulation models to predict insect development and optimize control timing.
Ortholepis
Ortholepis is a genus of small moths in the family Pyralidae, subfamily Phycitinae, established by Émile Louis Ragonot in 1887. The genus contains approximately 12 described species distributed across the Holarctic region, with records from Europe and North America. Species within this genus are associated with various woody host plants including birch, blueberry, and rhododendron. The genus has been subject to taxonomic revision, with some species transferred from related genera.
Pteroxanium kelloggi
Pteroxanium kelloggi is a bark louse species in the family Lepidopsocidae. It has a distinctive brownish-orange coloration with white spots. The species has been recorded from western Europe and Madeira, with additional distribution records from North America, South America, and Australasia. It feeds on a variety of woody plants including ash, cedar, gorse, ivy, larch, oak, pine, and yew, and has also been observed on rhododendrons and decayed wood substrates.
