Pachybrachis pinguescens
This record describes Pachybrachis pinguescens (species). Recorded family: Chrysomelidae. Recorded order: Coleoptera.
Identification and Appearance
Closely allied to californicus differing only as follows: Size larger, a little stouter, prothorax similarly strongly rounded in the male and distinctly more inflated in the female than in californicus , widest nearly at the middle in the female; type front less evidently impressed along the median line; antennae a little more slender. the tenth joint about four times as long as wide in the male; prothorax more finely and less closely punctate; front claws of male even more strongly enlarged.

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