Red-veined Darters coupled
More Red-veined Darters coupled
Red-veined Darter pairs stay together when "ovipositing" (laying/dropping eggs)
Like Common Darters, the Red-veined Darter male stays attached to the female and leads/protects her as she dips occasionally to drop/scatter eggs over the water
Another Red-veined couple
Not sure about this head-on pair -- could be Scarlet Darters?
