Living as we do at the edge of the forest, we share space with many wild creatures, large and small. Many are familiar: the deer and jack rabbits that browse on the hill, the frogs that call from the gutter downspouts, the hummingbirds that argue over nectar-filled flowers. Occasionally, we make a new acquaintance. This week it was a large dragonfly, noticeable for a long white tail and four dark wings that wave like flags.  A little research identified it as an adult male Common Whitetail (Libellula lydia). Its diet is mosquitoes and other flying insects.  An excellent neighbor to have around.
