Butterfly Color Patterns Reveal Clues About the Genes That Build Insect Wings

painted lady butterfly

By Viviane Callier Butterfly wings are natural canvases decorated with elaborate color patterns, but how these patterns develop and evolve is still incompletely understood. Now, a new study in Scientific Reports has identified the genetic code by which butterflies can assign color patterns to different parts of their wings during development. The code is based […]

Exotic Fruit Flies Found for First Time in Los Angeles

The species were not previously known to exist in the U.S. “I was as surprised as anyone when such unusual flies were […]

Mutational Chain Reaction Can Spread Throughout Insect Populations

By David O’Brochta A report recently published in Science describes a system by which one can introduce mutations into insect genomes and have those mutations quickly spread to all of the mutant’s progeny, and to all of their progeny’s progeny, and so on.The new system does not follow the standard rules of chromosome and gene […]
