This spring there have been a lot of these bronzey-green weevils in the garden. Unlike the Vine Weevil (Otiorhyncus spp) which mainly comes out at night, lumbers around quite clumsily and doesn’t fly; these weevils are very sprightly, abundant in daylight and readily fly (especially when you try and photograph them).
There are more than 400 species of weevil in the UK. Mostly, for the casual observer like me, they’re hard to identify. But I think these weevils may be Pea Weevils (Sitona lineatus, also known as the Pea Leaf Weevil and not to be muddled with the Pea Weevil of the US – Bruchus pisorum – which is one of the Bruchid Beetles or Bean Seed Beetles of the UK).
Adults Pea Weevils munch on plant leaves, making notches similar to, but smaller than, those of the Vine Weevil. However, the above ground damage is not usually significant: it is the larvae that feed in the nitrogen fixing nodules of legume roots that can cause damage to pea and bean crops.
Or maybe these little creatures are Common Leaf weevils (Phyllobius pyri).
The Watford Coleoptera Group has a fantastic gallery of UK weevils on their site and very detailed descriptions to help with identification. After looking through all those pictures and some descriptions, I think this is more probably the Common Leaf weevil (Phyllobius pyri) rather than the Pea weevil. But I’ll probably never be sure:)
