Bagous obliquus
Bagous obliquus is a species of true weevil in the family Curculionidae. It was described by LeConte in 1876. The species is known from North America, with records from Canada (New Brunswick, Ontario, Québec) and the United States. As a member of the large genus Bagous, it belongs to a group of weevils often associated with aquatic or semi-aquatic habitats, though specific ecological details for this species remain limited.
Bagous restrictus
Bagous restrictus is a small weevil native to North America that has become notable for its exclusive association with the invasive aquatic plant Hydrilla verticillata. It is the only native Bagous species known to utilize this introduced weed as a host. The beetle completes its entire life cycle within Hydrilla tissues, with larvae feeding and developing inside stems and tubers. Its native status and host specificity distinguish it from two introduced biological control agents (Bagous hydrillae and B. affinis) that also target Hydrilla.
Bagous transversus
Bagous transversus is a species of weevil in the family Curculionidae, described by LeConte in 1876. It is known from North America, with records from multiple Canadian provinces including Alberta, British Columbia, Manitoba, and Nova Scotia. The genus Bagous comprises aquatic or semi-aquatic weevils commonly associated with wetland habitats.
