Horsetail Grass and 2015

            I meant to post this during the summer, but never got around to it. Part of the swamp where great pains were taken not to allow the spread was this patch of horsetail grass. It may be a pest in other parts of NA, but here it was a refuge for two species of dragonflies: the Flame Skimmer and the Cardinal Meadowhawk. I've never seen any other insect perch on a blade, not even the less-than-fussy skimmer butterflies. Just remember that fossils of horsetail grass were from the same epoch as dragonflies, 330 million years ago. Must be something in the dragons' DNA that says, "Ah, home!" (Damselflies are "only" 270 million years old. They don't associate.)
