The Azure Hawker

Aeshna caerulea
The Azure Hawker is a boreo-mountain species and postglacial relict in some mountain ranges in Central Europe. In Poland, has a very small extent and is very rare. At present, only 1 locality has been confirmed, in the Równia pod Śnieżką Plateau (in the Karkonosze Mountains, Lower Silesia Province), at 1420-1430 m. It inhabits small water bodies in mountain peat bogs, subalpine or similar to them, situated at lower elevations. For the first time we observed this species in August 2011. Here are some photos (poor quality) and a short video from the meeting with this amazing, beautiful and rare dragonfly. The Azure Hawker is protected by law in Poland and listed in the Red List of dragonflies of Poland (category CR – critically endangered).
