Listronotus caudatus is a species of underwater weevil in the beetle family Curculionidae. It is found in North America. The species has been recorded in multiple Canadian provinces including British Columbia, New Brunswick, Ontario, and Québec. Very little is known about its specific biology or ecology compared to better-studied congeners such as the carrot weevil (L. oregonensis) and annual bluegrass weevil (L. maculicollis).
Listronotus hornii
underwater weevil
Listronotus hornii is a species of underwater weevil in the beetle family Curculionidae. It belongs to a genus that includes several economically significant pest species, though specific details about L. hornii's biology and ecology remain poorly documented. The species was described by Dietz in 1889.
Listronotus palustris
underwater weevil
Listronotus palustris is a species of underwater weevil in the beetle family Curculionidae. It is found in North America. The species epithet 'palustris' refers to marsh or swamp habitat, suggesting an association with wetland environments.
Listronotus scapularis
Listronotus scapularis is a species of underwater weevil in the beetle family Curculionidae. It is found in North America. The species is provisionally accepted in taxonomic databases and is distinguished from other Listronotus species by its aquatic or semi-aquatic habits.
Listronotus sparsus
Listronotus sparsus is an underwater weevil in the family Curculionidae, described by Say in 1832. It is one of relatively few weevil species adapted to aquatic or semi-aquatic habitats. The species occurs in North America, with records from Canada including Alberta, Manitoba, New Brunswick, and Nova Scotia. Like other members of the genus Listronotus, it likely has associations with aquatic vegetation, though specific ecological details remain poorly documented.
Listronotus teretirostris
underwater weevil
Listronotus teretirostris is a species of underwater weevil in the family Curculionidae, first described by J.L. LeConte in 1876. It is found in North America. The species belongs to a genus that includes several economically significant agricultural pests, though specific information about this particular species is limited.
