Nice! The first one is known as the Great Black Wasp (an odd common name), and I really like how you got the metallic blue to show on the wings. These big solitary wasps hunt katydids to feed to their young.
Thanks Mark for the feedback. I guess the Black wasp's wings have iridescence and the colors show if the sun shines on it 'just right'.
I am thinking of the same property as in the wings of a common grackle (bird).
