Dragonfly

Natural Habitat

Dragonflies are typically found near freshwater habitats such as ponds, lakes, rivers, and wetlands. Their larvae (nymphs) are aquatic, and adults stay close to water for hunting and reproduction.

Diet & Feeding

Dragonflies are predatory insects. Both adults and nymphs are carnivorous. Adult dragonflies primarily eat other flying insects, such as mosquitoes, flies, moths, and smaller butterflies, catching them in flight. Nymphs feed on aquatic invertebrates, including mosquito larvae, tadpoles, small fish, and other insect larvae.

Behavior Patterns

Adult dragonflies are agile fliers, known for their elaborate aerial hunting techniques. They are often territorial, especially males, who will defend their breeding grounds. Mating involves a unique 'wheel' formation. Females lay eggs in or near water. Their life cycle involves incomplete metamorphosis (egg, nymph, adult). Nymphs can spend several months to several years underwater. Adults typically live for a few weeks to several months.

Risks & Benefits

Dragonflies pose no risks to humans; they do not sting or transmit diseases. They are highly beneficial insects, acting as significant biological control agents against pest insects, particularly mosquitoes, both in their adult and nymph stages. They are also indicators of healthy aquatic ecosystems.
