There are several tiny, green, broad-snouted (weevils are usually known for their long snouts)
Leaf Weevils common over much of the UK, especially southern UK. They all look quite similar with a stripey, "knitted"
appearance and green colour, although the latter ranges from emerald and turquoise to brown-green and varies in the light.
Most are in the Phyllobius/Polydrusus species.
Shown with thumbnail and clover head to give indication of size. On oak/clover, this is likely
to be the Green Leaf Weevil - Phyllobius maculicornis,
Phyllobius virideaeris or
Polydrusus formosus, although
Polydrusus sericeus and the Nettle Weevil - Phyllobius pomaceus
look the same (the latter found mainly on nettles).
Polydrusus pterygomalis is another common arboreal weevil but
is browner green (less turquoise).
Climbing on my macro lens. The "knitted" rows show up better on macro.
