The insects are fueled by a packet of yellow abdominal fat, stored from their caterpillar days, that enables them to fly hundreds of miles without stopping. (That fat is responsible for the yellow streaks on your car windshield if you happen to run into one). When the fat reserve runs out, they will stop and breed. The next generation will continue the trek north.
