Which green weevil?


We were sitting in our middle clearing when caught this weevil on a June Sunday varying its diet with a bit of woolly jumper.

Very pretty, but who is it? No easy matter to identify weevils from a smartphone photograph. But we have some clues. Time for some internet detective work…..

It looks like one of the Entiminae broad-nosed weevils, and the ever-helpful  Nature Spot suggests one of either the Phyllobius or Polydrusus tribes. Another possibility would be Pachyrhinus lethierryi but it loves leylandii (someone must). Eakringbirds.com is detailed and helpful when identifying invertebrates in landscape like ours. It explains that in all Phyllobius , the antennal insertion point is viewable from above, whilst not visible from above in Polydrusus. Ours seems not to have insertion points on the top so maybe it’s a Polydrusus? Also, many Phyllobius have a tooth on their femora and ours hasn’t.

There are just the 10 Polydrusus to choose from – could it be Polydrusus formosus? It is common in England and eats young leaves and open blossoms of a wide variety of woodland trees and shrubs, fruit trees and hazel. We have masses of hazel coppice so that fits but who knows. Weevils can be are serious pests but there is plenty of hazel to go round, so you’re welcome to stay – whoever you are.
