[Note Guidelines] Photographer's Note
A female Common Sanddragon - Progomphus obscurus, obelisking to stay cool.

Common Sanddragon has a much wider range than Gray Sanddragon (P. borealis). It is slightly smaller with a complete midlateral thoracic stripe and a strong patch of brown basally in each wing. The thorax is pale yellow with a dark middorsal stripe widening anteriorly toward the collar and isolated from antehumeral stripe at its upper end. The humeral and antehumeral stripes are normally confluent at both ends with the thin pale stripe between them. The mid- and third lateral stripes are present and well-developed. The legs are short and darker than in Gray Sanddragon. The basal brown spot in each wing extends out generally to the first antenodal crossvein.

Hi Jim,
Great dragonfly shot! DOF is excellent and the focus is amazing. Such great detail around the head and eyes. Outstanding colors and perfect light. "Obelisking"... now that is a verb you don't hear very often.
TFS.
Ken
