Curculio venosus
This record describes Curculio venosus (species). Recorded family: Curculionidae. Recorded order: Coleoptera.
Identification and Appearance
A fairly large brown weevil, with females measuring around 7mm. It is quite similar to some other members of this genus and care should be taken with identification. Raised ridge of roof-like scales forming an obvious raised ridge at the elytral apex, scutellum longer than broad. 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. Widespread and fairly frequent in England and Wales.

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