Bilek's damselfly

The Bilek's damselfly (Coenagrion hylas) is probably the rarest damselfly in Central Europe! It is under the strictest protection and is the heraldic animal of the Tiroler Lech Nature Park!

Pale blue-black coloured This azure damselfly can be distinguished from all other damselflies by a broad black stripe on the abdomen. From 3 o'clock in the afternoon the Bilek's damselfly takes a "coffee break" and moves into the mountain forests. There it finds plenty of food and proves to be an excellent hunter. It is a very good weather flyer. It can only be observed in flight in fine weather and optimal flying conditions between mid-May and early August.

The Bilek's damselfly colonised clear mountain lakeswhich have a cold inflow and an outflow. It favours Shallow shore areaswhich with Sedges and horsetails are overgrown.

Their main distribution area is in Eastern Siberia. This is why it is also known as the "Siberian azure damselfly". In the Alps, around 8,000 kilometres away, it has found its second distribution area in Austria, particularly in the area of Lake Rieden.
