Blue Dasher
Pachydiplax longipennis

The Blue Dasher (Pachydiplax longipennis) is a common and widespread dragonfly over most of the U.S. except the Rocky Mountain area. The first two images on this page were shot in June, 2002, in Kenedy Co., Texas. Refer to captions below for the latter images. The male at right is obelisking which is a way to cool off by pointing the abdomen toward the sun thus exposing less of its body to the sun's heat.


 


 

The male on the right was photographed with a Canon EOS 1V and EF500 mm F4 L IS lens with a 2X and a 1.4X extender for 1400 mm on Fuji Velvia. It is remarkably sharp photo considering all the glass and magnification involved.
The photo on the right is of an immature male Blue Dasher and was a digital capture in the Angelina National Forest, Angelina Co., Texas in May, 2003. The camera was a Canon EOS 10D with an EF 300 mm F4 L IS lens and 1.4 X extender and 550 EX flash.
The photo here is of a female Blue Dasher at same time and place as the previous immature male.
The image here shows a female Blue Dasher ovipositing. Shot with same equipment as the previous shots in May, 2003, in Austin, Travis Co., Texas. It is quite a challenge to get photos of dragons in flight, but fun when you can do it.
