The big black and gold symmetrical spots on butterfly wings deter predators because they resemble eyes in the darkness, right? Not necessarily. Here's an experiment that indicates that we see eyes, but animals don't.
We all know that camouflage is an important tool in the evolutionary toolbox. But it's only one of the ways that butterflies and caterpillars use color to keep themselves safe.
Few infographs capture the liveliness of their subjects, but Eleanor Lutz's lovely chart of 42 North American butterflies reminds us that these are living beings as each butterfly flaps its wings.
It's brought whole new meaning to the phrase "Butterfly Effect."
Oregon's endangered silverspot butterflies typically pupate into chrysalises over the course of several hours, in a nocturnal process rarely observed by humans. But in this time-lapse footage, members of the Oregon Zoo's butterfly lab have combined over 15,000 photographs to compress the transformation into a matter…
Nature photographer Kjell Bloch Sandved has amassed a massive collection of butterfly and moth wings, capturing a host of unusual patterns. Using those patterns, he has assembled entire butterfly alphabets.
It sounds poetic, but it's apparently true: in the Amazon, bees and, more often, butterflies, flap around the heads of turtles to drink their salty, salty tears. It's truly a sight to behold.
For the past four years, photographer and biochemist Linden Gledhill has been taking macro focus shots of various butterfly and moth wings. Gledhill, who has also photographed natural and homegrown snowflakes, designed his own rig (with the help of Cognisys) to help create these intricate and beautiful close-up…
Chinese researchers have turned to the light absorbing properties of butterfly wings to significantly increase the efficiency of solar hydrogen cells, using biomimetics to copy the nanostructure that allows for incredible light and heat absorption.
Otters are already one of nature's most adorable animals. But what happens when you cross a romp of wiggly otters with a single butterfly? You get the cutest little butterfly chase you'll ever see.
For the first time ever, scientists have sequenced the genome of a creature who migrates long distances: the Monarch butterfly. The Monarch Genome Project hopes to provide insight into the butterflies' mysterious migratory pattern, which involves travel over great distances for several generations. How do these…
Animals seem to use migration to escape the spread of deadly pathogens...so it's bad news that many animals have stopped migrating.
Butterflies have an odd quirk in their mating practices: during warm months, the males pursue the females, but when it's cold, the females go after the males. This unusual reversal is a matter of life and death for the females.
Every four generations, Monarch butterflies create a "super generation" that lives long enough to migrate to Mexico. In this video from National Geographic, we see how the butterflies engineer their children for such astonishing longevity.
