Which insect holds its wings outstretched when resting?

Explanation:
Wing posture when resting is a clue to how the insect moves and functions. Dragonflies keep their wings outstretched, held flat or slightly angled, even while perched. This setup matches their powerful flight system and the need to launch into flight instantly from a standstill. Damselflies, in contrast, typically rest with their wings together over the abdomen, making them look more compact. Butterflies usually rest with wings folded upright or closed over the back, not spread flat, and beetles keep their wings hidden under hard, protective covers (elytra). So, the insect that holds its wings outstretched when resting is the dragonfly.
