Summertime is skimmer time

Refer to the Dragonflies of Northern Virginia Calendar of Flight Periods by Kevin Munroe, former manager at Huntley Meadows Park. Notice the flight period for most Skimmers (Family Libellulidae) is centered on June, July, and August. Since meteorological summer is defined as June, July, and August, summertime is skimmer time.

A female Slaty Skimmer dragonfly (Libellula incesta) was spotted during a photowalk at Occoquan Bay National Wildlife Refuge, Prince William County, Virginia USA, as indicated by her mostly black femora, brown face, and terminal appendages.

Female Slaty Skimmers have a pair of flanges beneath their eighth abdominal segment (S8) that are used to scoop water when laying eggs (oviposition), hence the family name “Skimmer.”

Female Slaty Skimmer dragonflies and female Great Blue Skimmer dragonflies (Libellula vibrans) look similar. The following blog post provides guidance regarding key field markers that can be used to differentiate the two species: Great Blue Skimmer dragonfly (young female).
