Oberea schaumii
This record describes Oberea schaumii (species). Recorded family: Cerambycidae. Recorded order: Coleoptera.
Identification and Appearance
Per Lingafelter, first two or three abdominal sternites nearly completely dark (at least at center), remainder pale yellow or testaceous, rear top of head usually dark, posterolateral pronotal spot usually larger than the central spot. Det. M. A. Quinn, 2016 the descriptions of Oberea schaumii, caseyi, pruinosa in Lingafelter and Yanega are in disagreement with each other.

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