Faked out!

A Blue Corporal dragonfly (Ladona deplanata) was perched on a tree alongside Wildlife Loop trail at the North Tract of Patuxent Research Refuge, Anne Arundel County, Maryland USA. This individual is an immature male, as indicated by its lighter coloration and terminal appendages.

My good friend Mike Powell and I were searching for Harlequin Darner (Gomphaeschna furcillata). At first glance, we thought we might have found our first Harlequin; after a closer look, we realized we’d been faked out by a Blue Corporal.

Another Blue Corporal dragonfly was perched on the great red spot of the planet Jupiter. Kidding! Seriously, Blue Corporals typically perch on the ground — this dragonfly was perched on a wooden boardwalk near a small pond.

The last two individuals are mature males, as indicated by their darker coloration and terminal appendages.

Predator-prey relationship?

There is some speculation that Blue Corporal dragonflies might prey upon Harlequin Darners, so Mike and I weren’t happy to see lots of mature Blue Corporals in our target search area. For what it’s worth, we hunted intensively for Harlequin Darner for hours and found only one individual; G. furcillata was described as “relatively abundant” two-to-three weeks earlier at the same location, before Blue Corporal began emerging.
