It's Halloween!?
This male HALLOWEEN PENNANT has taken up the OBELISK stance in order to keep it's internal temperature down on this 95 degree day. It's abdomen is pointing directly at the sun and it's forewings are held higher than the hind wings in this typical perching stance. The Halloween Pennant is the largest Indiana Pennant and gets it's name from the black and orange coloration of it'd wing pattern and body. Female Halloween Pennants are yellow and it is not uncommon to see males and females in open areas far from water.

On the other hand, this CALICO PENNANT has assumed a "Reverse" OBELISK stance to accomplish the same temperature reduction. Note that the reed he is perched on also has the remains of the exoskeleton from the last molt, to adulthood, of another dragonfly nymph (left) and the remains of the exoskeleton of a damselfly nymph on the opposite side of the reed.
