This is a Fat-legged flower beetle (Oedemera nobilis). They are a beautiful shiny metallic green colour, but only the males have those amazing thighs. They might look a bit fierce but they only feed on pollen. This one was about 1cm long.
This is a gorgeous photo. The shades of greens are amazing especially on the beetle. You are right about the metalic green. Man could never duplicate that color. Fav
