This appears to be a Sky-blue
Groundstreak Kisutam syllis from the
NBC in Mission, Hidalgo county, Texas on December 02, 2010. A
small non-Calycopis hairstreak with apparent blue on the wings in

obtained in any photos. I took these pics the next day, and the
flight shot - while poor - shows the DORSAL side with the insect
flying away from the camera (the dorsal innermost basal HW orange
spots confirm this). The annotated version of the flight photo
(bottom image) show the areas of blue as expected on a female K.
syllis; I suspect that the blue on the HW
appears very pale due to the wings moving at a faster rate than
the thorax:
