Unseasonably warm and cold days can prolong the active period of moths and butterflies by nearly a month. "The results are not at all what we expected."

Some moths use ultrasound to warn bats they contain bitter toxins; others are just trying to sound like they'd taste bad, too.

A new tiny drone called Smellicopter uses a live moth antenna to navigate toward smells. It can also avoid obstcles in the air.

Tiny sensors that weigh less than jellybeans and ride on the back of moths may help researchers study places too dangerous for people to get to.

A new therapy that relies on a moth-infecting virus and nanomagnets could repair genes that cause diseases like cystic fibrosis and sickle cell.
