Bembidion bifossulatum
This record describes Bembidion bifossulatum (species). Recorded family: Carabidae. Recorded order: Coleoptera.
Identification and Appearance
The large punctures on elytra and entirely dark antennae are helpful features. This species is restricted to the far west versus similar B. b. cheyennense that ranges toward the east (Maddison 1993). However, Y. Bousquet (pers. comm.) currently prefers to treat the latter as B. cheyennense based on distinct morphologic differences.

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