This record describes Scaphinotus guyotii (species). Recorded family: Carabidae. Recorded order: Coleoptera.
Identification and Appearance

Largest and most variable species of Steniridia . Elytra markedly convex and relatively large compared to body. Color variable: violaceous-black, black, green-black, with or without aeneous reflections. Front tarsi of male very narrow and with much reduced pad of setae on first segment. Median lobe of aedeagus distinctive - markedly constricted at base . Range encompasses both sides of French Broad River, which normally serves as an effective barrier to other flightless mountain species .

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