Why do dragonflies use their wings?

How do dragonflies keep their bodies warm?
Like all insects, dragonflies are technically ectotherms ("cold-blooded"), but that doesn't mean they're at the mercy of Mother Nature to keep them warm or cool. Dragonflies that patrol (those that habitually fly back and forth) employ a rapid whirring movement of their wings to raise their body temperatures. Perching dragonflies, on the other hand, who rely on solar energy for warmth, skillfully position their bodies to maximize the surface area exposed to sunlight. Some species even use their wings as reflectors, tilting them to direct the solar radiation toward their bodies. Conversely, during hot spells, some dragonflies strategically position themselves to minimize sun exposure, using their wings to deflect sunlight.
How long does it take for a dragonfly to molt?
When a nymph is finally ready for adulthood, it crawls out of the water onto a rock or plant stem and molts one final time.

Until their bodies fully harden they are weak flyers, making them ripe for the picking. Birds and other predators consume a significant number of young dragonflies in the first few days after their emergence.
