Wind and warmth can improve travel time for the billions of insects worldwide that migrate each year, according to a first-ever radio-tracking study by University of Guelph biologists.
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 more about what happens to insects during their physically taxing migration period may help in efforts to conserve them, particularly threatened species, said the researchers.
The study, which was recently published in Biology Letters, found wind and temperature are more important influences than precipitation for bugs on autumn migration flights spanning thousands of kilometres between their breeding and wintering grounds.
