Sphaerion exutum

This record describes Sphaerion exutum (species). Recorded family: Cerambycidae. Recorded order: Coleoptera.

Identification and Appearance

This tropical species was first recorded from the U.S. on the basis of eight specimens collected on dead ebony at Bentsen-Rio Grande Valley State Park in May, 1972 and May, 1973 (Giesbert and Hovore 1976). An additional male specimen was taken at that locality on dead Acacia in May, 1980. (Hovore et al. 1987)

About Primitive Winged Insects: the wider group

Order-level background for Coleoptera, the group containing Sphaerion exutum. 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.
