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 timewe observedthis speciesin August2011.Here are somephotos (poor quality) anda short videofrom the meeting withthis amazing,
beautiful andrare dragonfly. The Azure
Hawker is protected by law in Poland and listed in the Red List of dragonflies
of Poland (category CR – critically endangered).
Aeshna caerulea male; this species is dependent on sunshine to be fully active; frequently perches on bright reflective surfaces, such as trunks, sticks and rocks, allowing the sun to heat its body

OH WOW! That is a lifer here on this blog! Thanks a million, guys, for sharing this amazing and all too rare footage! Not only the photos are magnificent and very professional, but you went really in depth to show the appendages of both sexes and you managed an incredible video of the mating wheel and its phases of copulation, plus the environment where the species evolves. I am truly in awe! Congratulations, I share this straight away on G+!!
WOW! WOW! WOW! That's great, that's brilliant, that's wonderful! This is not a simple article, but the real monograph! And sites are magnificent and make dream! By looking at Dijkstra, I learnt that the male of this species changed color according to the ambient temperature, what is clear on pic 4, where the male is grey! Thank you for this sharing, and this new species in our Pantheon! Greetings, M.
Yes Morikan, you have right. The male of A. caerulea changes color according to the ambient temperature. In the morning, when is cold and the sun is not shining strongly, his colors are gray and violet (photos 2-4), later when the sun heats the heavily, male is blue. Thanks for all nice words, Mo! Greetings
Bonjour, Quel plaisir de regarder des photos d'une Libellule que je n'aurai jamais la chance de rencontrer. Les photos montrent parfaitement le changement de couleur du mâle, de plus c'est vraiment super de nous présenter un coeur copulatoire en photo et en vidéo sans compter la ponte de la femelle. Je suis également sensible à la beauté du plateau où tu rencontre Aeshna caerulea, c'est un biotope magnifique. Merci pour le partage de ces rares et très belles photos. Amicalement.
BRAVO les amis !!!! Le biotope en plus comme cadeau, c'est un endroit superbe et cela nous fait toujours plaisir de connaître leurs lieux de vie. Je vous envie. Quelle superbe série. Encore bravo pour ces photos chez nous !
