    Mosquitoes may surf winds above Africa more than we realized

    VANCOUVER — Adult female mosquitoes could be surfing air currents high above the West African Sahel. This traffic, at least 40 meters up, might be troubling news for efforts to control malaria.

    Traps attached to balloons flown over villages in Mali caught close to 3,000 mosquitoes at heights between 40 and 290 meters above the ground, where winds might blow the insects long distances....

    Each year painted lady butterflies cross the Sahara — and then go back again

    Move over, monarchs. The painted lady butterfly (Vanessa cardui) now boasts the farthest known butterfly migration.

    Though found across the world, the orange-and-brown beauties that live in Southern Europe migrate into Africa each fall, crossing the Sahara on their journey (SN Online: 10/12/16). But what happened after was a mystery because the butterflies disappeared. Researchers...

    Flying insects tell tales of long-distance migrations

    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.

    Menz, an ecologist at the University of Bern in...

    Long-ignored, high-flying arthropods could make up largest land migrations

    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...

    Painted lady butterflies’ migration may take them across the Sahara

    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.

    No single monarch...
