Bird Nest Carpet Beetle
Anthrenus isabellinus
This record describes Anthrenus isabellinus (species). Recorded family: Dermestidae. Recorded order: Coleoptera.
Identification and Appearance
Eyes notched in front, antennae 11-segmented, with club of 3 segments. Scales of dorsal surface black, white and red (or yellow). White scales forming some small spots, and a wide transverse band in anteriour half of elytra; or white scales dominant. Difficult to separate from related taxa in its native range; occurs in two distinct color forms: f. dorsatus f. isabellinus The dorsatus form is dominant in North America, and has been taken for A. pimpinellae insofar . However, male genitalia are markedly different; externally, both species can be separated most easily by the underside :

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