Spangled Skimmer Dragonfly (Libellula cyanea)



Spangled Skimmer Dragonfly (Libellula cyanea)

A bit torn and tattered, but still able to catch insects like this Spotted Cucumber Beetle removed from our garden.


Spangled Skimmers are common in eastern North America as far west as Kansas and Texas.  Males are blue.  Females are brown with yellow stripes.  They prefer well-vegetated ponds and lakes and slow-moving sections of streams.  (BugGuide)

Eastern Pondhawk - Male

.
Female and young male Eastern Pondhawks are green with square, black spots on their abdomens.  As they age, males turn blue.  This male Pondhawk photographed by Jo is still showing just a little bit of green on its thorax.  BugGuide has and excellent series of photos showing both male and female Pondhawks are various stages of development.

Although we live up on a rocky ridge, there are evidently enough stock ponds around to provide suitable dragonfly habitat.

Common Green Darner (Anax junius) -- Male


(Photo by Jo on 10/18/09)



A common dragonfly found throughout the United States and most of Canada. The large black spot in front of the eyes is distinctive for this species and is found on both males and females. Please see BugGuide for more identification characteristics.

A close up of the genitalia indicates this is a male Common Green Darner. For comparison, please see this image of female genitalia on BugGuide.

Adult A. junius are strong fliers and can be found just about everywhere, though they do have a preference for area near larval habitat: Still marshy waters, fresh and slightly brackish. We've seen several of these dragonflies over the past few days though our ridge does not qualify as prime larval habitat. I suppose they were just migrating through our area.
