Cool Dragonflies


Normally dragonflies perch with their tails lying perpendicular to the ground as seen on the left.  The dragonfly on the right has its tail pointing straight up.  Why?  This is one of the ways that dragonflies stay cool, especially during our hot Southeast Texas summers.  With its tail pointing upward it reduces the amount of surface area exposed to the sun thereby reducing body temperature.
