Rare: butterflies like Plebejus idas, also known as the northern blue


The number of endangered plant and animal species worldwide reached a new record this year, reports WWF. In Switzerland, more than 40% of insect species are considered threatened. 

If not halted, the loss of pollinating insects like bees and butterflies will become a problem throughout Europe.
