Butterfly

Tropical butterflies have evolved to fend off a deadly parasite.

Greenland was once carpeted in lush forests, a new study shows.

A germ that kills males triggers a vicious cycle of increasing female promiscuity and male sexual exhaustion in a species of butterfly, scientists now find.

A beetle with scales as pale as a ghost could help engineers come up with super-thin, paper-white paints, new research shows.

Scientists have now discovered that metalmark moths in Costa Rica use mimicry to escape hunters as well, by mimicking the very predators that might normally eat them.

Some butterflies within a species are stronger than others, and more able to colonize new areas. And they happen to be more fertile, too.

Creation of new species through hybridization was thought to be common only in plants, and rare in animals.

Cold and wet conditions could cause some species to disappear from the state.

Butterflies burn a tremendous amount of fat while hibernating during the transformation from a caterpillar.

The beautifully colored wings manipulate light using engineering tricks similar to those found in the light emitting diodes used in digital displays.

The monarch tracks the angle of sunlight to find its way.

Record migration expected.

This blue-winged creature teaches scientists a thing or two about light and color.
