The dragonflies are swarming my neighborhood this week.

Dragonflies are fun to watch because they often return to the same perch over and over, giving you the opportunity to observe them closely.

Watch the abdomen on this one.

It has tipped its abdomen up into what is called the “obelisk posture.”

It is possible that it saw my camera as a threat and this was a defensive move. On the other hand, it was a hot day and scientists have suggested the obelisk posture is a way dragonflies adjust their exposure to sunlight and keep from overheating.
