Guides
Xyleborus viduus
Xyleborus viduus is a species of bark beetle in the family Curculionidae, first described by Eichhoff in 1878. It is native to North America and belongs to a genus containing numerous ambrosia and bark beetle species, many of which are economically significant forest pests. The species is provisionally accepted in taxonomic databases, indicating some uncertainty regarding its current classification status.
Xyleborus xylographus
Xyleborus xylographus is a species of bark beetle in the family Curculionidae, first described by Thomas Say in 1826. It belongs to the tribe Xyleborini, which includes ambrosia beetles that cultivate symbiotic fungi in wood galleries. The species has been recorded in North America, the Caribbean, and Southern Asia. Like other members of its genus, it likely engages in fungus-farming behavior, though specific ecological details for this species remain limited in published literature.
Xylechinus montanus
crenulate bark beetle
Xylechinus montanus is a species of crenulate bark beetle described by Blackman in 1940. It is a member of the weevil family Curculionidae and has been recorded in North America, with distribution records from Alaska and western Canadian provinces including Alberta, British Columbia, and Saskatchewan. As a bark beetle, it is likely associated with woody vegetation, though specific ecological details remain limited.
Xyloterini
Xyloterini is a tribe of ambrosia beetles within the subfamily Scolytinae (Curculionidae). Members are characterized by fungal cultivation behavior and association with woody host plants. The tribe includes genera such as Xyloterinus and Indocryphalus. Xyloterinus politus, the type species of Xyloterinus, attacks black oak trees and maintains mutualistic relationships with ambrosia yeasts including Candida xyloterini, a yeast species named after this beetle tribe.
Zascelis
hidden snout weevils
Zascelis is a genus of weevils in the family Curculionidae, commonly referred to as hidden snout weevils. The genus was established by John Lawrence LeConte in 1876 and contains more than 80 described species. These beetles are part of the largest family of beetles, with the genus representing a relatively small but established lineage within the weevils.
Zascelis irrorata
Zascelis irrorata is a species of hidden snout weevil in the family Curculionidae. The species was described by John Lawrence LeConte in 1876. It is known from North America. As a member of the hidden snout weevils, it belongs to a group characterized by particular morphological adaptations of the rostrum.
Zygobaris
flower weevils
Zygobaris is a genus of flower weevils in the beetle family Curculionidae, established by John Lawrence LeConte in 1876. The genus contains eight described species, all native to North America. These weevils are associated with flowering plants, though specific ecological details remain poorly documented. The genus is rarely encountered in collections and has received limited study beyond taxonomic description.
Zygobaris nitens
Zygobaris nitens is a species of weevil in the family Curculionidae, first described by John Lawrence LeConte in 1876. It is a North American species with a single iNaturalist observation record, indicating it is rarely encountered or poorly documented. The genus Zygobaris belongs to the superfamily Curculionoidea, the largest group of weevils. Limited information exists regarding its biology, habitat preferences, or ecological role.
Zygopini
twig and stem weevils
Zygopini is a tribe of weevils in the family Curculionidae, commonly known as twig and stem weevils. The tribe contains more than 20 genera and at least 250 described species. The majority of diversity occurs in the Neotropics, with 8 genera endemic to South America and 11 genera extending north of South America. Two genera have been recorded from Africa. Members are associated with woody plant tissues.
