Here the visitors can witness a spectacular phenomenon which occurs only rarely in nature The butterflies live in the valley during the summer, mate and fly away in September leaving their eggs at various points around the island.
In April these eggs produce the small larva which are transformed into chrysalis in May and achieve their final form at the beginning of June.
When it turns hot they leave the locale where they were born and travelling by night, reach the valley where they will stay until September.
They are actually adult insects that follow the waterways and migrate here to reproduce, females leave for other suitable areas to lay their eggs in the early fall, due to the high humidity of the area.
They are attracted by the smell of the resin as well as the coolness of the surroundings which does not change even during the hottest days of summer.
