Dorytomus filirostris
This record describes Dorytomus filirostris (species). Recorded family: Curculionidae. Recorded order: Coleoptera.
Identification and Appearance
A slender, long‑snouted weevil specialised for life on poplars and willows - particularly Black Poplar and Hybrid Black Polar. It is 4-5mm (excluding the long rostrum) and tawny brown with the upper side covered in patchy pale and decumbent (lying flat) pubescence. The rostrum is only slightly curved. There is a small tooth on each femur, with the front femoral tooth being larger than the others. This is a rare beetle and identification needs to be confirmed with the County Recorder. All year but especially in May and June. No additional images available for this species.

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