Dragonfly

Dragonflies are insects belonging to the order Odonata, a group that has existed for more than 300 million years. Today, over 3,000 dragonfly species are known, living on every continent except Antarctica. They are most often found near ponds, lakes, rivers, and wetlands because their young develop in freshwater.

A dragonfly has a long, slender body, two pairs of transparent wings that move independently, and large compound eyes that provide nearly 360-degree vision. These features make it one of the most agile flying insects. Dragonflies are skilled predators throughout their lives. Aquatic larvae hunt small invertebrates, tadpoles, and even tiny fish, while adults catch mosquitoes, flies, and other insects in mid-air using their strong legs to form a basket around their prey.

Unlike butterflies, dragonflies do not pass through a pupal stage. Their life cycle includes three stages: egg, aquatic larva, and adult. Depending on the species and environmental conditions, the larval stage may last from several months to several years before the insect climbs out of the water and transforms into its winged form.

Adult dragonflies usually live only a few weeks or months, spending that time feeding and reproducing. They play an important ecological role by helping regulate insect populations and by serving as food for birds, frogs, fish, and spiders. Because dragonflies depend on clean freshwater habitats, scientists often use their presence and diversity as indicators of the health of rivers, ponds, and wetlands.
