Dragonflies are flying insects. In the summer, dragonflies can be seen perched on tree branches in an obelisk pose (i.e., a handstand position with the tip of their abdomen pointing upward). In 3–5 sentences, describe how dragonflies might control their body temperature and give reasons for why they might perch in this pose...
Dragonflies perch in the obelisk pose to control their body temperature. By pointing their abdomen upward, they can reduce the surface area exposed to direct sunlight, which helps prevent overheating. This posture also allows them to maximize the surface area available for evaporative cooling, as any breeze passing over their bodies will help to dissipate heat. In addition, perching in this pose may help them regulate their metabolic processes and maintain optimal functioning in the hot summer weather.

Dragonflies stand on tree branches with their butt held high in the air to stay cool in the summer. By doing this, they can keep their bodies from getting too hot and help themselves cool down faster. This pose also lets them use the wind to help them stay cool and keep their bodies working well in the heat.
