Here’s another test photo with the ring flash adapter, and probably better as a test. It can be very difficult to get enough light on shiny insects without having a harsh reflection of the flash. In this case, there is some reflection down the middle of the back, but it isn’t too bad.
The insect itself looks like a nymph (immature) stink bug, but I don’t know which one. There are at least a dozen species on the island but I’ve only been able to find photos of immature specimens for a few of them. This is quite common. Because they undergo metamorphosis, insects have multiple life stages that are often very different in appearance (egg, larva, pupa, adult or egg, nymph, adult). Truly understanding these animals requires recognizing the adult as well as several other forms. Perhaps the best way to develop this knowledge is to rear insects to adulthood, but with hundreds of species, this is a huge undertaking.
