I made this vlog this week:
And it raises the question of how butterflies get from A to B when they are at the whim of capricious gusts of wind. Apparently, it's all about wing size to body mass ratio.
Because the wings are so big, they make it easier for the whole insect to manoeuver. A butterfly’s huge wings are like having a massive rudder - the bigger the rudder, the faster the ship can turn. If you have a little rudder, you can’t turn as fast.
It also seems that their aopparently erratic fluttering pattern is deliberate - this makes it very hard for predators to predict.
Every day is a school day.
