I encountered these insects on the edge of the forest in Northern Costa Rica. At first I thought they were some sort of beetle, but I found the same plants also had what seem to be nymphs of the same species. Searching for some ID for them online I came up empty. My guess is some sort of shield bug.
You have two distinct insect orders represented in your request, and at least two, and possibly three different species. The “metallic green bug” is actually a Tortoise Beetle, and we believe it is in the genus Omocerus based on an image we located on The Befuddled Loris (scroll down) and verified on the Coleoptera of Costa Rica where it is identified as Omocerus casta. This same beetle can also be found on the Smithsonian Tropical Research Institute and Discover Life.
The other two creatures are Hemipteran nymphs and we believe they are different species. They are most likely Stink Bugs in the family Pentatomidae.
Well that clarifies things a bit. I found several of each kind of the insects I sent images of in the same small area, so I thought they must be of the same species. Thanks for taking the time to respond.
