Dragonflies are dependent on ambient temperature to warm or cool their bodies. On cool days dragonflies will align themselves perpendicular to the sun's rays in order absorb as much of the sun's energy as possible.This Slaty Skimmer perches with it's thorax and abdomen perpendicular to the sun in order to collect the maximum warmth needed for it's activities.
On hot sunny days dragonflies will point their abdomen directly at the sun in order to minimize the surface area of their bodies exposed to the sun.
This Blue Dasher is in the position called OBELISKING in order to expose the least amount of surface area to the sun and lowering it's body temperature.
