New Distributional Data of Butterflies in the Middle of the Mediterranean Basin: An Area Very Sensitive to Expected Climate Change

Butterflies are known to be very sensitive to environmental changes. Species distribution is modified by climate warming with latitudinal and altitudinal range shifts, but also environmental perturbations modify abundance and species composition of communities. Changes can be detected and described when large datasets are available, but unfortunately only for few Mediterranean countries they were created. The butterfly fauna of the Mediterranean Basin is very sensitive to climate warming and there is an urgent need of large datasets to investigate and mitigate risks such as local extinctions or new pest outbreaks. The fauna of Calabria, the southernmost region of peninsular Italy, is composed also of European species having here their southern range. The aim of this dataset paper is to increase and update the knowledge of butterfly distribution in a region very sensitive to climate warming that can become an early-warning area
