Wasp Beetle
Clytus arietis
This record describes Clytus arietis (species). Recorded family: Cerambycidae. Recorded order: Coleoptera.
Identification and Appearance

Though this beetle mimics a wasp, in both colouration and movement, this black and yellow beetle is totally harmless. On hedgerow vegetation and in well wooded areas. It breeds in the decaying wood of deciduous trees. It can often be found in clear view, resting on leaves in low vegetation. Presumably its yellow and black colours warn off any predatory birds! Common and widespread in England and Wales, scarcer in Scotland.

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