Thank you very much! :-)
Of the 6 pictures shown at the beginning of the page, the one on the bottom right of that group looks to be a perfect match for my garden pests. Guessing it’s the Green Stink Bug.
Maybe they cane with the corn-borers that destroyed my sweet corn? Hard to say.

Produces 1-3 generations per year depending upon the climate. Sounds like Stink bugs will eat borer larvae. (What do they eat when they run out of Larvae?)
Good luck!
