Orchids, a world of colors in the Aezkoa valley


The orchids are, and have always been very striking plants (in the form of flowers and their color), not only for insects,  also for humans too.



 Orchis purpurea
 While in Europe, its length is less than in the tropics, have always had great appeal and what has been discovered later about them, probably caused greater fascination.
His name is related to the tubers with roots as a form it represents. Theophrastus was who named them "Orchis" by the resemblance to the testicles of men. The first orchid  known is dated 65 million years ago, then at the time of the dinosaurs existed orchid species.

The research works of Darwin, on the reproductive mechanism of plants, especially in the study of orchids,  discovered  us the relationship between pollinating insects and orchids: as the result of this bestiality, created flowers are attractive products, means of decoy and also viscous and sticky pollen.
Several species began to have rewards such as food (nectar and oils) and decoy (mimic the shape and smell of female bees, wasps or flies). So some species were eventually specializing in one pollinator to ensure a more efficient pollen transfer.
This is why so extremely varied forms of orchid flowers that attract bees, wasps, flies, butterflies, moths and other parts of the world including birds, bats and frogs.


 Orchis scolopax

The Aezkoa Valley(Navarre) provides a variety of orchids, its intricate relief allows  to create numerous microclimates within this transition from Pyrenean to Atlantic climate. We have many forests within the valley but also numerous grassland or "larreak" some at your disposal N and others in a position S. Not all bloom at the same time, so we have made ​​the list based on their flowering.
   In late May and early June several species begin to bloom Cephalantera genus like and some Orchis.

 Platanthera bifolia 
 Hymantoglossum hircinium
   
       In late June, the Anacamptis gives way to forest orchids that in the Irati Forest are of the genus Epipactis.
