Every autumn, a quiet mountain pass in the Swiss Alps turns into an insect superhighway. For a couple of months, the air thickens as millions of migrating flies, moths and butterflies make their way through a narrow opening in the mountains. For Myles Menz, it’s a front-row seat to one of the greatest movements in the animal kingdom.

Forget honking Vs of geese or gathering herds of wildebeests. The biggest yearly mass movements of land animals may be the largely overlooked flights of aphids, moths, beetles, flies, spiders and their kin.
About 3.5 trillion arthropods fly or windsurf over the southern United Kingdom annually, researchers say after analyzing a decade of data from special entomological radar and net...
Butterflies look so delicate as they flitter from flower to flower. And yet, they are capable of migrating incredibly long distances. The monarch, for example, migrates between Canada and Mexico, covering distances of up to 4,800 kilometers, riding a combination of columns of rising air, called thermals, and air currents to travel around 80 to 160 kilometers per day.
