Abstract: T ypical biotopes inhabited by the dragonflies’ larvae are rivers, creeks, streams, lakes, ponds, bogs, as well as tanks in excavation pits. It turns out, however, that there are species of dragonflies resistant to severe environmental conditions, capable of living in very unusual habitats. There are species inhabiting waterfalls, saline water or even temporary desert pools. Several tropical species inhabit “plant-held waters” - phytotelmata – water bodies in leaves, roots, tree hollows. There are also terrestrial or semi-terrestrial dragonflies, which are adapted to live in moss, on wet rocks or ground litter. The diversity of habitats and adaptations of dragonflies related to these harsh conditions is enormous. These dragonflies enrich the ecosystems, as an important component of food webs, and their presence certainly increases the aesthetic value of the landscape. The importance of protecting these extraordinary developmental habitats is crucial in context of the conservation of the odonata fauna. 42
