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 ...

Amazonian Heliconius butterflies have a distinctive coloring, known as the “dennis red patch” and the “ray red streaks” on each side of the wing. These colors come from different genes that derived ...

Getting your Trinity Audio player ready... Engineered mutant butterflies give a glimpse deep into the genetic roots of wing patterns, an international team reported Monday in the Proceedings of the ...

Native to the Philippines, the Scarlet Mormon is known for its rich red patches that stand out sharply against its black wings. Males show brighter colours, while females mimic toxic species to avoid ...

New research on butterfly genomes has revealed that the genetic components that produce different splotches of colour on wings can be mixed up between species by interbreeding to create new patterns, ...

They're invading by the millions — swarms and swarms of them, their black and orange masts fluttering against the spring air from Cape May to Sussex in one of the greatest butterfly migration in ...

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 ...
