When resting, a butterfly holds its wings together above its back; a moth holds its wings horizontally. And butterfly antennae are thickened, or clubbed, at the tips, while moth antennae are most commonly straight or ... WebOct 6, 2014 · Sequencing the genomes of monarch butterflies from around the world, a team of scientists has now made surprising new insights into the monarch’s genetics. They identified a single gene that appears central to migration—a behavior generally regarded as complex—and another that controls pigmentation.
