Coenagrion pulchellum (Variable Bluet/Variable Damselfly)

The curiously named Variable Bluet/Damselfly – curious because most Coenagrions exhibit a certain amount of variability in their black markings.

We made our inaugural trip to the excellent Wicken Fen rather late in the 2011 season. I was hoping to see my first Variable Damselfly and lo, it delivered. We found a pleasing flush of these characters on our return to Norfolk after many years in 2013, pleasing because they are not a species that features locally.

Id Notes

  • bears the Coenagrion “spur” on the side of the thorax
  • antehumeral stripes are classically broken resembling exclamation marks
  • ♂ – S9 more than half black
  • ♂ – black mark on S2 resembles a stemmed wine glass (but the stem can be missing, apparently)
  • ♂ – black mark on S9 resembles a vampire bat (perhaps a little fanciful)
  • ♀ – two forms, dark and blue, best identified by the pronotum shape [Ed: good luck!]
male
