Which butterflies travel the furthest to get home in the spring?

The Monarch butterfly travels the furthest of

all insects. It makes a return journey of 8,000

km every year from its homeland in Canada to

Mexico.

The monarch is the only butterfly known to make a two-way migration as birds do. Using environmental cues, the monarchs know when it is time to travel south for the winter. Monarchs use a combination of air currents and thermals to travel long distances. Some fly as far as 3,000 miles to reach their winter home!
