Phyllobius glaucus

Phyllobius glaucus is a species of weevil found across Europe, especially in carrs. It is a pest of a variety of fruit trees, but has little economic effect. It was first described by Giovanni Antonio Scopoli in 1763.

Description

[edit | edit source]

Adults grow to 8–12 millimetres (0.3–0.5 in) long. The body is black, but is covered with elongate, hair-like scales that give the animal a very variable, greenish-brown appearance. The legs are reddish brown.[1]

Distribution

[edit | edit source]

Phyllobius glaucus is common and widespread in Europe.[2][3] A single specimen of P. glaucus (under the name P. calcaratus) has been recorded from Canada, but this is thought to be an error.[4]

Ecology and life cycle

Phyllobius glaucus is associated with a wide range of trees and shrubs, and is a minor pest of fruit trees, including apples, pears, cherries and plums.[1] The insects chew small holes in the leaves and petals of the trees.[1] It is a typical component of the fauna of alder carr in northwestern Europe.[5]

Taxonomic history

Phyllobius glaucus was first described by Giovanni Antonio Scopoli in his 1763 work Entomologia Carniolica, under the name Curculio glaucus. A second species was later named Curculio glaucus, but has since been renamed to Coniocleonus glaucus.[2] Taxonomic synonyms of Phyllobius glaucus include:[3][6]
