Listroderes costirostris
This record describes Listroderes costirostris (species). Recorded family: Curculionidae. Recorded order: Coleoptera.
Identification and Appearance
L. costirostris is currently restricted to CA and rarely from western AZ. All other North American vegetable weevil specimens are currently L. difficilis [that name will be changed soon], and are misidentified in most collections as L. costirostris . ‒C.W. O'Brien, quoted in

About Primitive Winged Insects: the wider group
Order-level background for Coleoptera, the group containing Listroderes costirostris. Species-specific details appear above.
Group overview
Coleoptera is the largest order of insects with over 400,000 described species, representing ~25% of all known animal species and ~40% of all insects. In the U.S. alone, nearly 30,000 beetle species have been identified.
Ecological role of the group
Beetles are prominent decomposers, especially in forests, breaking down dead wood and recycling nutrients. As predators, they reduce populations of pest insects. Many species are also important pollinators of flowering plants.
Economic and practical significance of the group
Beetles have major economic significance: leaf beetles (Chrysomelidae) and weevils (Curculionoidea) are among the most destructive agricultural pests globally, costing billions annually, while predatory species like ladybugs provide natural pest control.
