Beware of look-alikes!

Several Bar-winged Skimmer dragonflies (Libellula axilena) were spotted on 10 June 2016 at a vernal pool located in Huntley Meadows Park (HMP).

The first individual is an immature male. Notice the white “frosting” at the base of his hind wings — one of several key field markers for Bar-winged Skimmer.

The last individual is a mature male. His body (thorax and abdomen) is covered completely by blue pruinescence that masks the coloration he displayed as an immature male.
