Why do dragonflies and damselflies need water to begin life?
Quick Answer
Their young stage is aquatic, with nymphs living in ponds, lakes or streams. Water provides food and shelter before they emerge as flying adults.
The Full Story
Dragonflies and damselflies are hemimetabolous insects, meaning they develop through incomplete metamorphosis. Eggs hatch into aquatic nymphs, which live underwater for months or years depending on the species. These nymphs are predators, feeding on small aquatic animals before crawling out of the water and transforming into winged adults. Water is therefore essential to their life cycle, not just a habitat preference. Because of this dependence, they are often useful indicators of freshwater ecosystem health.
