Rivest This summer, if you see a butterfly with wings that are blue on top with orange spots underneath, you may have crossed paths with a male European Common Blue (or Polyommatus icarus), a newly introduced species in Canada. Could it be […]

A glasswing butterfly feeding at flowers in Costa Rica. The remarkable transparency of these butterflies allows them to be “invisible,” and the antiglare coating of their wings helps to prevent them from being given away by any glare of sunlight off their wings.

A new conservation plan weighs the burden and interests of landowners, biologists, and butterfly enthusiasts alike. Monarch butterflies cover a tree at El Rosario Monarch Butterfly Sanctuary in Michoacán, Mexico.D. André Green II D. André Green II is an assistant professor of Ecology and Evolutionary Biology at the University of […]

Described by the ‘father of zoogeography’ and co-author of the theories of evolution and natural selection, the species hasn’t been reexamined since 1866. An over a century-long mystery has been surrounding the Taiwanese butterfly fauna ever since the “father of zoogeography” Alfred Russel Wallace, in collaboration with Frederic Moore, authored […]

The black patches on the wings of some butterflies are 10 to 100 times darker than everyday black objects.

Infrared photographs of butterflies, where brightness correlates with the capability of radiative cooling. Credit: Nanfang Yu and Cheng-Chia Tsai/Columbia Engineering Researchers discover that butterflies have specialized behaviors and wing scales to protect the living parts of their wings; nanostructures found in the wing scales could inspire the design of radiative-cooling […]
