Rambur’s Forktail damselfly (female)

December 16, 2016

A Rambur’s Forktail damselfly (Ischnura ramburii) was spotted at Mason Neck West Park, Fairfax County, Virginia USA. This individual is an immature heteromorph female, as indicated by the reddish-orange coloration of her thorax and abdominal segments one and two (S1-2), and reddish-orange postocular spots; her coloration will become duller as she matures. Andromorph females are colored like males.

This sighting was another reminder of one of many Walterisms: Don’t be dismissive! Huh? Male Rambur’s Forktail damselflies look similar to male Eastern Forktail damselflies (Ischnura verticalis). Eastern Forktails are relatively common, especially during spring and early-summer. Common. That’s the key word. When I noticed several male Rambur’s Forktails at the water retention pond I thought, “Oh, Eastern Forktails. Nothing to see here, folks. Move along.” Fortunately I spotted the immature heteromorph female and realized the error of my ways.

I’ll say it again: Don’t be dismissive — that kind of thinking can result in missed opportunities for wildlife photographers. I never expected to see Rambur’s Forktails at Mason Neck West Park and my preconceptions almost caused me to miss a golden opportunity to see a relatively uncommon damselfly.

The following photo shows a male Eastern Forktail damselfly (Ischnura verticalis) spotted along “Great Blue Heron Trail,” Accotink Bay Wildlife Refuge, a 1,200 acre preserve located at Army Garrison Fort Belvoir, Fairfax County, Virginia USA. Eastern Forktails are somewhat similar in appearance to Fragile Forktail damselfies (Ischnura posita).
