Phymatodes nigrescens

This record describes Phymatodes nigrescens (species). Recorded family: Cerambycidae. Recorded order: Coleoptera.

Identification and Appearance

Phymatodes nigrescens is in fact distinct from these dark forms of P. vulneratus as well. It can be separated from both bicolored and unicolored forms of P. vulneratus by the coarsely punctate apical one-half of the elytra; the overall more coarsely, sparsely punctate elytra; and the narrower, sinuate antemedian fasciae. Phymatodes vulneratus has impunctate, rugose elytral apices; more finely and densely punctate elytra at the basal one-half; and thinner, more linear, parallel-sided antemedial fasciae. habitus photos Known host: Pseudotsuga menziesii menziesii

About Primitive Winged Insects: the wider group

Order-level background for Coleoptera, the group containing Phymatodes nigrescens. 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.
