This record describes Sitona suturalis (species). Recorded family: Curculionidae. Recorded order: Coleoptera.
Identification and Appearance
Length 4 or 5 mm. A brown weevil with rather a dark and light striped appearance when fresh. There are other weevils with a similar appearance and detailed examination is necessary for identification. Other Sitonia species. Dissection is necessary to distinguish between them. Unless identified by a recognised expert, photographic evidence is required and the specimen should be examined with a microscope. In the comments box, state the key or ID method used. Note the beetle's size and describe the identifying characters. It is advisable to retain the specimen in case further checks are needed.

About Primitive Winged Insects: the wider group
Order-level background for Coleoptera, the group containing Sitona suturalis. 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.
Recorded sources for this group: Britannica, Smithsonian, NCSU Entomology. Imported estimates may describe particular regions or reporting periods.
