This is another of the green Phyllobius weevils, the most common of which is Phyllobius pomaceus. Phyllobius argentatus is a smaller species (Size around 4 to 6mm), and usually a brighter golden green colour. Under a lens it has round scales and is covered with fine white hairs. It also has pale red/yellow femora. The front femora are relatively swollen with a large tooth.
Several of the other Phyllobius beetles are very similar and are best distinguished with a lens. P. argentatus can be identified by the combination of round scales and the yellow/red toothed femora. See our ID Aid below.
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.
Whilst commonly an arboreal species found on broadleaf trees it can also be found on low herbaceous vegetation such as nettles.
