Dragonfly

Natural Habitat

Dragonflies are found globally, typically near freshwater sources such as ponds, lakes, rivers, streams, and wetlands. Their aquatic nymphs require clean, stable water bodies for development.

Diet & Feeding

Both adult dragonflies and their aquatic nymphs are predatory. Adults primarily feed on other flying insects such as mosquitoes, gnats, flies, and sometimes smaller butterflies. Nymphs feed on aquatic invertebrates, tadpoles, or small fish.

Behavior Patterns

Dragonflies are expert fliers, capable of flying forwards, backward, and hovering. They are diurnal hunters and spend much of their day actively seeking prey. Males are often territorial and will defend prime hunting or breeding grounds. They undergo incomplete metamorphosis; the aquatic nymphs (naiads) emerge as adults after several molts.

Risks & Benefits

Dragonflies pose no direct risk to humans, as they do not sting or bite. Their significant benefit lies in their role as biological pest control, consuming large numbers of nuisance insects like mosquitoes and flies, which can vector diseases. They are also indicators of healthy aquatic ecosystems.
