Hi Bug Man….
a search on your webpage suggests that these are Small Milkweed bugs. Is the one in the upper left hand corner also a small Milkweed bug (perhaps a WEE small milkweed bug)? Or is it another species altogether? The bugs were found, appropriately, on a swamp milkweed pod.
Great photo. These are all Small Milkweed Bugs, Lygaeus kalmii. The smallest is an immature nymph that will grow wings at the final molt.
