Identification and Appearance

2.4-2.9mm. Generally black with weak metallic elytra. Legs are black. The scutellum is round. Amongst the Ceratapion weevils, this species is distinguished by the rugose sculpture on the frons (between the eyes). Unless identified by a recognised expert, photographic evidence is required and the specimen should be examined with a microscope. In the comments box, state the key or ID method used. Note the beetle's size and describe the identifying characters. It is advisable to retain the specimen in case further checks are needed. Mainly found in grassland where it is usually found on Thistles, but not restricted to them and can be found on other plants. All year round, but most frequently recorded in summer. Widespread in England and Wales, less well recorded in Scotland. No additional images available for this species.

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