The shade-loving Shadow Darner (Aeshna umbrosa) is a common species of resident dragonfly in the lower Susquehanna basin.  Females deposit their eggs on aquatic vegetation in clean still waters, including those found in marshy sections of streams, beaver ponds, and even, on occasion, garden pools, as long as they aren’t overpopulated with large fish.  Shadow Darners are the most likely of the dragonflies to be noticed cruising in search of prey at dusk and are the last to be seen during the season, sometimes still found hawking small insects on warm days in November.  As you may have guessed, they are quite fond of consuming mosquitoes.
