Phyllobius oblongus

This record describes Phyllobius oblongus (species). Recorded family: Curculionidae. Recorded order: Coleoptera.

Identification and Appearance

Brown Leaf Weevil - Phyllobius oblongus
FeatureDescription
Additional details4 - 5.5 mm. Brown elytra, lacking scales but with many erect hairs.
LegsLegs pale.
HeadHead, pronotum and underside black. Phyllobius is a genus of broad-nosed weevils that are commonly found on low herbage and in trees during spring and summer. Most are covered in metallic green scales that give them a very attractive appearance. There are 9 species and most look similar but they can be separated by carefully comparing the range of features shown in the table below, either under a binocular microscope or with a x20 hand-lens. Phyllobius weevils can be distinguished from the similar genus Polydrusus by looking where the antennae emerge from the rostrum. In Phyllobius the antennae emerge from the top whilst in Polydrusus they are positioned at the side. When looking directly down on the beetle it is usually clear to see. Unless identified by a recognised expert, good photos are required that show the key ID features. Also state the beetle's size in the comments box. Woodland, copses, wooded parkland and hedgerows. Adults occur during spring and early summer. Widely distributed and generally common throughout England and Wales and extending to west Perth in Scotland.

About Primitive Winged Insects: the wider group

Order-level background for Coleoptera, the group containing Phyllobius oblongus. 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.
