Researchers use drones and satellite photos to document illegal logging in monarch butterfly reserve
The monarch butterfly has been called “the Bambi of the insect world.” These fascinating insects are famous for their bright colors and their incredible fall migratory route, which can be as long as 2,500 miles. Starting from as far north as Canada, millions of monarchs take a two-month journey to a mountain range that straddles the border of two Mexican states, Michoacán and México, where they spend the winter.
