Butterfly migration to be tracked

Scientists hoping to find out more about the monarch butterfly’s annual migration are hoping to join the creature in its journey this year. Every year millions of the orange and black insects

fly 4,828 km from Canada to Mexico for the winter. Experts don’t really understand why the butterflies do this. The insects will be tracked by an ultra-light plane carrying the team. The plane, which is painted red and black to look like a monarch butterfly, will take off from Montreal on 20 August. The journey following the butterflies is expected to take 75 days. When the butterflies fly north, they lay eggs and then die near the borders of Mexico and the US, and the US and Canada. The next generation of insects then continues the journey. But monarchs make the flight back down south in just one journey. — AP
