Great Blue Skimmer dragonfly (immature male)

The preceding photograph shows a Great Blue Skimmer dragonfly (Libellula vibrans) spotted on 14 May 2013 during a photowalk at Accotink Bay Wildlife Refuge, a 1,200 acre preserve located at Army Garrison Fort Belvoir, Fairfax County, Virginia USA.

This individual is an immature male, as indicated by its coloration and terminal appendages. Notice the immature male Great Blue Skimmer dragonfly resembles the female of the same species.

Males often go through an immature stage in which they are patterned much like females but then change dramatically at maturity by adding a layer of pruinosity (a powdery bloom much like the one we see on plums) to part or all of their thorax and abdomen. Most pruinosity is whitish to pale blue. Source Credit: Paulson, Dennis (2011-12-19). Dragonflies and Damselflies of the East (Princeton Field Guides) (Kindle Locations 696-698).
