Donacia cinerea
This record describes Donacia cinerea (species). Recorded family: Chrysomelidae. Recorded order: Coleoptera.
Identification and Appearance

7.5 to 11 mm. Most easily identified among the UK Donaciinae by the finely and densely pubescent dorsal surface which gives the species a silky or grey appearance in the field. Elongate with sub-parallel elytra, entirely dull bronze or, occasionally, with a distinct green reflection. Please provide a close-up photograph. Detailed examination may be required to safely confirm this species. Usually seen resting on, or flying between, the foliage of aquatic and amphibious plants at the margins of freshwater. Most likely to be encountered from May to August. Both larvae and adults feed mainly on Bulrush species. Formerly much more widespread and common in the U.K. it is now local and generally rare throughout England and Wales. No additional images available for this species.

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