The colors and patterns of black swallowtails reveal the diversity of evolutionary dynamics acting on the sexes and the various life-history stages Six species of swallowtail butterflies occur locally ...

This article was originally featured on The Conversation. Patterns on animal skin, such as zebra stripes and poison frog color patches, serve various biological functions, including temperature ...

Color patterns play central roles in the behavior of insects, and are important traits for taxonomic studies. Here we report striking and stable structural color patterns—wing interference patterns ...

Similarities in how different organisms look can indicate a close evolutionary relationship. Conversely, great differences in appearance can suggest a very distant relationship, as in many adult ...

Heliconius charithonia is one of the species of butterflies whose wing patterns scientists scrutinized to better understand the evolutionary process. This butterfly is wild-type; the genetically ...

Mother lizards can induce different color patterns in their offspring in response to social cues, reports research published June 10 in the online early edition of the journal Ecology Letters. Female ...

An international team of scientists working with Heliconius butterflies in Panama was faced with a mystery: how do pairs of unrelated butterflies from Peru to Costa Rica evolve nearly the same ...

Six species of swallowtail butterflies occur locally, and they combine yellow, black, orange, blue and red in several diverse patterns that invariably catch the eye. We can marvel at them, but our ...
