Green Leaf Weevil - Phyllobius maculicornis
One of many similar green weevils. It has elongate scales and a covering of fine, pale setae. It has a tooth on the femora which are dark coloured under the scales. The elytral striae are clearly visible (lacking scales) and the apex of the scape is dark.
It is very similar to Phyllobius pomaceus but can be identified with a lens through the combination of elongate scales and dark, toothed femora. (P. pomaceus has oval scales). 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.
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.
It is found mainly in broadleaf trees.
April onwards.
Widespread and fairly common in Britain.
Occasional in Leicestershire and Rutland.
Eakring Birds has a useful introduction to Phyllobius weevils.
