Hornet or wasp.

[Woodsman]

Sitting outside this morning and Mr Nasty here was on a peony bud next to me. Not sure if its a hornet or a wasp. I just know I don't like it.

Horrible lookin creature whatever it is........

Wasp. Hornets are much bigger and have different coloring/eyes.

The wasp can be your friend.

Nice shot.
