Libellula luctuosa
Its face is pale yellow or brown in females and young males, but darkens to black along with the top of the head in mature males. The pterothorax is dark brown with a pale yellow middorsal stripe that extends onto the prothorax. This area becomes obscured with brown color in females and black in mature males, ultimately turning powder blue. The sides are pale yellow with an ill-defined dark stripe on the third lateral suture. This area becomes obscured in females and turns a dark brassy brown in older males. There are large black bands on the wings that extend basally to the nodus in both sexes. The wingtips are occasionally darkened, especially in females and western-individuals. Mature males develop a white area beyond the basal dark stripe that extends to the wing apex. The legs are black. The abdomen is only moderately depressed and tapers rearward. It is pale yellow with broad black middorsal and lateral stripes. The yellow is interrupted only by a black carinae. Segment 8 in females is slightly expanded laterally. The caudal appendages are black. The color of the abdomen darkens in both sexes and becomes powder pruinose blue in males.
Brushy area of greenbelt.
