An Obelisk Posture

The obelisk posture is a handstand-like position that some dragonflies assume to prevent overheating on sunny days. The abdomen is raised until its tip points directly 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.
