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.(4 points)

Answer 1

Dragonflies are ectothermic insects, meaning they rely on external sources to regulate their body temperature. By perching in an obelisk pose, where their abdomen is raised, they can minimize exposure to direct sunlight on their body while allowing heat to escape from their abdomen, effectively cooling themselves down. This position also helps maximize sun exposure to their wings and thorax, which can warm their flight muscles, improving their agility and ability to hunt. By controlling their temperature through these behaviors, dragonflies can maintain optimal physiological performance during the warm summer months.

Answer 3

Dragonflies are ectothermic insects that regulate their body temperature by perching in an obelisk pose, raising their abdomen to minimize sun exposure and allow heat to escape. This position maximizes sun exposure to their wings and thorax, warming their flight muscles for improved agility. By controlling their temperature in this way, dragonflies maintain optimal performance during warm summer months.
