Your stinkbug looks very much like the "Florida Predacious Stinkbug", Euthyrhynchus floridanus.

Your flash photo makes the insect look greener than most images that show the bug quite dark. In some images the upper two yellow spots merge into one spot.

These are beneficial stinkbugs, not plant eaters/suckers.

Thanks for the id, Larry. I didn't use flash but the pic was taken in bright sunlight. I removed some of the green and the bug shows a lot darker.

Here is a link that might be useful: good bug

That's likely it; the references I read mentioned some variation in the general body color. Nice images.
