DOES WIND AFFECT BUTTERFLY MIGRATION?

Despite their size, migrating butterflies, including red admirals ( right) are not at the mercy of the wind. In fact, recent research using vertical-looking radar shows that they make maximum use of windy conditions. By selecting the most favourable tailwinds, often at altitudes of 400m or more above the ground, butterflies can reach speeds of 50kmph – and can even correct for crosswind drift.
