Damselflies on White Rock Creek, July 2012

From Google Earth ref; 32°57'13.79"N  96°48'36.86"W a track leads down to the White Rock Creek. It was a slow start since I turned 50 this week and had a little party to mark the occasion last night. The short cycle ride had started my blood moving again, picking up the sludge which had settled in my sump and sending it straight back to my head, which reacted by thumping.

Thankfully there were very few birds to stop me as I cycled along beside the stream in the pleasant shade. The few that did catch my attention did not merit photographs. Carolina Chickadees, Tufted Titmice and Downy Woodpeckers showed themselves briefly and a Green Heron flushed from the river bank.


I only stayed for a short while and most of my time was spent in a patch of grass looking at damselflies. The one above I shall take to be a Comanche Dancer, Argia barretti.


The Powdered Dancer, Argia moesta  were very common, but I am taking this identification with a pinch of salt. It is not a perfect fit for the field guide specimen, but I can’t see a better alternative. The juvenile/female, below,  corresponds quite well.


The Blue-ringed Dancer, Argia sedula was another common ode that did not quite match its description in the book.


Especially when the colour matches between individuals varied so.


Also seen along the creek and in a nearby pond were Swift Setwing, Dythemis velox, Eastern Pondhawk, Eurothemis simplicicollis, Black Saddlebags,Tramea lacerata ,and Eastern Amberwing, Perithemis tenera.

Birds seen;
Great Egret 1, Green Heron 1, Eurasian Collared Dove 2, White-winged Dove 2, Mourning Dove 2, Downy Woodpecker 1, Blue Jay 10, American Crow 4, Carolina Chickadee 4, Tufted Titmouse 6, Great-tailed Grackle 60.
