Cardinal Meadowhawk again. Note the posture of the wings, and reddish legs.
Four-spotted Skimmer, Libellula quadrimaculata, male.
Another male, of the Four-spotted Skimmer, Libellula quadrimaculata. It starts flying in late April, which makes it one of the earliest dragonflies. It is common around acidic water, so not unexpected in the bog.
Three males of three species, fighting over the prime perch.
Perhaps not so plain.
