Author 'Gilbair' (Id 235343 ) : Not far from the aerodrome of Montricher is a 'protected wetland' which flow various small streams which are nearly dry in summer. The area is covered with forest, whose thick canopy lets through small lit areas. This is where I surprised this group of piérides in the process of 'pumping' of 'mineral water' in the area still muddy a creek almost dry : you can see the trunk of the first butterfly in the process of 'drink' !
