abstract:The Valais (; , ) is one of the 26 cantons of Switzerland, situated in the southwestern part of the country, around the valley of the Rhône from its headwaters to Lake Geneva, separating the Pennine Alps from the Bernese Alps. The canton is one of the drier parts of Switzerland in its central Rhône valley.
But through the cooperation of local farmers, vineyard owners and conservationists, Valais is becoming a sanctuary for these highly endangered insects.
