Question

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 regulate their body temperature through behaviors such as basking in the sun and adjusting their posture to control heat absorption. When perched in an obelisk pose, the dragonfly minimizes its surface area exposed to direct sunlight, allowing it to prevent overheating while still absorbing heat through its abdomen. This pose not only helps to maintain an optimal body temperature for flying and hunting but also conserves energy during hot summer days. Additionally, by elevating their abdomen, they might enhance airflow and facilitate cooling when needed.
