Lynn pm'ed to take a look at the topic, but i see John already gave the answer i got in mind seeing the picture as well.
So I second John.

However i've only seen them with bright green stripes, where they are looking blueish here.
But the eye coloration and placing of the stripes makes me think of O.septentrionalis as well.
Over time they will change coloration.

Perhaps if you can catch it, you can see if you are able to see blue bones on the ventral side of the hind legs.
