Butterflies migrate by car
Researchers studies the optimum habitat of two species of butterflies, the marbled white (Melanargia galathea) and the small skipper (Thymelicus sylvestris). The optimum areas proved to be located much further up north, at a distance to great to travel on their own. Between 1999 and 2000, butterflies were captured and brought by car to their new home. The ‘assisted colonization’ all went according to plan. Migration by car may be able to help other animals as well when their surrounding becomes less and less suitable for them.
The research was held in cooperation of three British universities (Durham, York en Leeds), the Centre for Ecology and Hydrology and the Butterfly Conservation. The results are published in Conservation Letters.
