A new study shows the dragonfly Pantala flavescens migrates as much as 8,000 miles round-trip between India and Japan. Researchers say the findings show the potential of using stable isotopes to track insect migrations.
A new review of ant research illuminates how ant behavior is driven by a cascade of individual decisions among colony members. Insights on ant movement and encounter rates also suggest parallels to collective behavior in another population under the microscope in 2020: humans.
Trick or treat? From colorful ornaments to foamy bubbles to piles of "junk," a variety of insects wear clever disguises that protect or hide them from predators. Learn about several of these insect ensembles—and perhaps find some inspiration for your next Halloween costume.
