Only a few species of dragonfly do hibernate as adults. The winter damsels hibernate in heathland and will start reproducing as soon as nice weather sets in at march or april.
Other dragonfly will be present as eggs (Spreadwings) or in nymph stages. The eggs are sometimes in plants along the side of the water, even tree branches (Western Willow Spreadwing). The Spreadwings have an apparatus to drill holes in plants to put there eggs there. Most dragonflies lay eggs in the water or just at the shore mostly hidden in the vegetation. Soon a nymph emerges and it lives as an aquatic predator until the next year mostly. The nymphs crawl out of the water and in most cases climb in reeds where they attach themselves with crossed feet. They emerge from their last nymph skin and pump up their wings and abdomen with air.
