Another specialty species of this site is the libellulid Dythemis fugax, the Checkered Setwing. Below are images of a female (right, dorsal view; lower left, lateral view): This species is one that I had also collected in Cherokee County at the Mined Lands WA, where it occurs with a congener, D. velox.
Right is a picture of a ponded area in the drainage channel below the diversion dam. In normal times, the water passes through the river channel, and only in floods is it diverted into the drainage channel, so these ponds are only occassionally fed by the river. Below left is a view of the river channel upstream of the dam.
These pictures of the site made in the evening of 26 July, 2000.
At 2030 on that date, there were a few Epitheca (Epicordulia) princeps and Pantala flavescens (male, right; female, below left) flying around. This species is truly cosmopolitan, and can be seen almost everywhere in the world. I have seen it in Belize and Thailand, so even though it is a common species, it can remind you of home when you are traveling and of exotic places when you are home.
Also, as I walked around the sandy scrub,
Libellula luctuosa, Erythemis
simplicicollis (female, below right), and Dythemis fugax were flying when disturbed from
Below left and right are images of male D. fugax. Note that the male has a bright red face and deep mahogany eyes, and does not have the smoky wing tips that characterize the female.
Along the river below the dam there are areas where grasses line the bank. These are favored spots for the beautiful calopterygid damselfly Hetaerina americana. Here is a photo of a tandem pair, with the male opening his wings to display a warning flash of ruby red color at other passing males (below, left). To the right is a scanned lateral view of a female (top) and male (bottom).
Another damsel found in this area is the coenagrionid species Argia moesta, the Powdered Dancer. Here is a female:
