Overwintering as Nymphs. Not many insects are active in the winter, but the nymphs of dragonflies, mayflies and stoneflies live in waters of ponds and streams, often beneath ice. They feed actively and grow all winter to emerge as adults in early spring.
Why is a dragonfly metamorphosis considered incomplete?
It’s called an ‘incomplete metamorphosis’ because there’s no pupal stage within their life cycle. Wikipedia has details: The larval stage of dragonflies lasts up to five years in large species, and between two months and three years in smaller species.
