Common Leaf Weevil

Phyllobius pyri

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

Identification and Appearance

Common Leaf Weevil - Phyllobius pyri

5 to 7 mm. The legs are reddish brown with a strong leg tooth. The elytra are coppery in fresh specimens becoming blacker with age and have a ribbed appearance. This is the only Phyllobius species that has blade-like ridges on its tibiae. The large leg tooth, rufous legs and the sharp edge to the tibiae help to distinguish this species. If found in trees it also helps to separate it from other Phyllobius weevils many of which live in lower herbaceous vegetation. 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, 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. Found on a range of trees and shrubs in parks, gardens and woodland edge. One of the most common broad-nosed weevils it is widespread in Britain.

About Primitive Winged Insects: the wider group

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

Recorded sources for this group: Britannica, Smithsonian, NCSU Entomology. Imported estimates may describe particular regions or reporting periods.
