Understanding which butterfly species migrate is critical to planning for their conservation, because management actions for migrants need to be coordinated across time and space. Yet, while migration appears to be widespread among butterflies, its prevalence, as well as its taxonomic and geographic distribution are poorly understood.
Millions of Monarch butterflies migrate each year, but sadly their numbers are declining at a worrying rate. To protect them, the El Rosario Monarch Butterfly Reserve in Mexico was designated a UNESCO World Heritage site in 2008, as the concentration of overwintering butterflies there was deemed "a superlative natural phenomenon".
