What Is a Dragonfly?
Dragonflies are predatory insects in the suborder Anisoptera. They are among the oldest insect groups on Earth and are well known for their speed, hovering ability and striking appearance.
What Do Dragonflies Eat?
Dragonflies are carnivorous insects that feed mainly on mosquitoes, flies, moths and other small insects. Both adult dragonflies and their aquatic young are predators, helping control insect populations around freshwater habitats.
Dragonfly Habitat & Distribution
Dragonflies are found worldwide except Antarctica. They are most common near freshwater habitats such as ponds, rivers, lakes, marshes and wetlands because their young develop in water.
Dragonfly Life Cycle
Dragonflies go through a multi-stage life cycle beginning as eggs laid in or near water. They hatch into aquatic nymphs, which live underwater and hunt other small creatures. After growing through several stages, they emerge from the water and transform into winged adults.
How Do Dragonflies Fly So Well?
Dragonflies are exceptional fliers thanks to their lightweight bodies, strong flight muscles and ability to move their wings independently. This allows them to hover, dart, turn sharply and even fly backwards in some situations.
Why Are Dragonflies Important?
Dragonflies are important predators in both aquatic and terrestrial food webs. They help reduce pest insect numbers and are often used as indicators of water quality and wetland health.
Are Dragonflies Good for Gardens?
Dragonflies can be beneficial in gardens and outdoor spaces because they eat mosquitoes and other flying insects. Gardens with ponds or nearby water may attract more dragonflies and support local biodiversity.
Conservation & Environmental Threats
Dragonflies can be affected by pollution, habitat destruction, wetland drainage and declining water quality. Because many species depend on healthy freshwater systems, they are useful indicators of environmental change.
