Guides
Orthochaetes
Orthochaetes is a genus of weevils in the family Curculionidae, tribe Styphlini, established by Germar in 1823. The genus has Palearctic origins, with at least one species, Orthochaetes setiger, documented as an adventive introduction to North America. Records from Canada indicate establishment in Newfoundland and British Columbia. The genus is characterized by morphological features distinguishing it from other Styphlini genera, requiring modified identification keys for North American fauna.
Orthoptochus squamiger
Orthoptochus squamiger is a species of broad-nosed weevil in the family Curculionidae, subfamily Entiminae. First described by Casey in 1888, this species is known from a very limited number of observations and museum records. It belongs to the tribe Peritelini, a group of weevils primarily associated with woody plants. The species appears to be restricted to the southwestern United States and adjacent Mexico.

Pachnaeus litus
blue-green citrus root weevil, blue-green citrus weevil
Pachnaeus litus is a broad-nosed weevil in the family Curculionidae, commonly known as the blue-green citrus root weevil or blue-green citrus weevil. It is a pest of citrus in North America, with eggs that serve as hosts for multiple parasitoid wasp species. The species has been studied extensively for biological control potential, particularly targeting its egg stage with parasitoids such as Brachyufens osborni (Trichogrammatidae), Pediobius irregularis, and Horismenus bennetti (Eulophidae).
Pachylobius
pine weevils
Pachylobius is a genus of pine weevils in the family Curculionidae, established by LeConte in 1876. The genus contains at least two described species: Pachylobius picivorus (pitch-eating weevil) and Pachylobius stupidus. Species in this genus are associated with coniferous hosts and have been documented as pests of pine regeneration in forest ecosystems.
Pachylobius picivorus
pitch-eating weevil, pitch eating weevil
Pachylobius picivorus, commonly known as the pitch-eating weevil, is a pine root-feeding weevil native to North America. The species is an economically significant pest of natural and planted pine seedlings, with brood development requiring 100–128 days during summer. Adults are long-lived and oviposit continuously at approximately 0.7 eggs per day per female throughout their lifespan. Populations exhibit two annual peaks in the Georgia Piedmont, driven by temperature and developmental cycles. Behavioral studies indicate the species responds strongly to olfactory cues, particularly ethanol and turpentine mixtures, though visual cues are less important for host location than in related species such as Hylobius pales.
