Ceutorhynchus inaffectatus
This record describes Ceutorhynchus inaffectatus (species). Recorded family: Curculionidae. Recorded order: Coleoptera.
Identification and Appearance
Rather big, grey Ceutorhynchus , dorsal scales narrow (no ovate scales intermixed) in double rows on elytral intervals (diagnostic vs. C. rapae ). Pronotum well convex in both directions, cushion-shaped, without lateral tubercle like as in Glocianus , and with midline impressed. Also, no trace of a preapical hump on elytra. The similar European C. napi has denser scaling (compare C. rapae ); C. contractus , an import for biocontol of Garlic mustard, is much smaller and has unusually short apical tarsomere. earliest record in our area: 1931

About Primitive Winged Insects: the wider group
Order-level background for Coleoptera, the group containing Ceutorhynchus inaffectatus. 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.
