Green Immigrant Leaf Weevil - Polydrusus sericeus. I see these every year and I take a picture every year, but they are a nice metallic green.

This weevil is European in origin and first found in New York in 1906. They are reported to feed on leaves of trees such as apple, birch, oak, pear, poplar, strawberry and willow. They are rarely considered a pest.
