Obelisk

Koh Samui, Thailand

The obelisk posture is a handstand-like position that some dragonflies and damselflies assume to
prevent overheating on sunny days. The abdomen is raised until its tip points at the sun, minimizing
the surface area exposed to solar radiation. When the sun is close to directly overhead, the vertical
alignment of the insect's body suggests an obelisk.Smart little fellows!
