What is a Libelle?

Libelle is the German word for dragonfly, an important and beautiful member of the insect order Odonata, suborder Anisoptera. The ancestors of today's species flew over 300 million years ago in the forests of the Carboniferous period, during which today's hard coal was formed. They experienced the appearance of dinosaurs 265 million years ago and survived their disappearance 65 million years ago. Today, about 5,600 species are known worldwide, divided into two main groups, the large and the small dragonflies. A peculiarity among insects are the dragonfly's wings. The wings can be moved individually and independently of each other, allowing spectacular flight maneuvers. They can remain in one spot like helicopters, and certain individual species can even fly backwards. Water plays a central role in the life of dragonflies. Like all insects, dragonflies develop from eggs. A larva hatches from the egg, which metamorphosizes itself several times. The larvae of all dragonfly species live in water. The eggs are therefore laid directly in, or in the immediate vicinity of, a body of water. The adult larva leaves the water, and out of this last larval stage hatches the dragonfly in its finalized form as a flying insect. In contrast to other insect groups, such as flies or butterflies, the dragonfly has no pupal stage. Humans usually meet dragonflies at their water breeding grounds, where you can observe the individual species and make exciting observations about their behavior. The occurrence of the individual species gives good information about the condition of the respective habitat, which makes dragonflies excellent bioindicators. It is therefore necessary to closely monitor the development of the populations and take protective measures. By protecting dragonflies, we will ultimately be able to preserve entire biotic communities and thus contribute to a better environment.
