Phyllobius virideaeris

Phyllobius virideaeris

Description

Length 4 or 5 mm. A bright metallic green or bluish nettle weevil. Phyllobius virideaeris lacks the femur teeth found on the majority of UK Phyllobius species. 

Similar Species

It can be distinguished from the similar P. roboretanus by the gently sloping rear end and also by examining underside.  P. roboretanus only has a thin covering of fine scales, with much of the underlying surface visible. In P. viridiaeris the underside is densely coated with round scales, the same as the upperside. Phyllobius virideaeris  also appears rather later in the year.

Identification difficulty
Identification aids

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.
