Wind, warmth boost insect migration

Source: Science Daily

Researchers equipped monarch butterflies and green darner dragonflies with radio transmitters and tracked them through southern Ontario and several northern States to learn how environmental factors affect daytime insect migration. Learning about what happens to insects during their migration may help in conservation efforts. The study found wind and temperature are more important influences than precipitation for bugs on autumn migration flights spanning thousands of kilometers between their breeding and wintering grounds.
