How did eyespots on butterfly wings evolve? By recruiting gene networks already at work in the body to build antennae, legs, and even wings, research finds.

In hotter climates, male dragonflies don't develop their trademark wing pigmentation. That could make it harder to find a mate, researchers say.

Birds that struck buildings in Chicago are now in a museum, where researchers are investigating earlier migrations, bird body changes, and any link between.

A complex network of wing, muscle, and nervous system genes give fruit flies what it takes to become champion fliers.

Birds can learn to recognize fast and flashy butterflies they've failed to catch in the past—as well as similar-looking species—research finds.

Researchers have identified a new species of praying mantis after discovering imprints of its fossilized wings in present-day Quebec.

A bird- and bug-inspired wing design could keep wind and other obstacles from batting around small fixed-wing drones and boost their battery efficiency.

To extract nectar from flowers while in flight, moths depend on precise, millisecond timing between their brain and muscles.

The way a mosquito uses its wings to make special sounds to attract a mate could lead to ways to build quieter drones, researchers say.

A super sturdy kind of metal foam outperforms aluminum in tests to determine its suitability for the leading edge of airplane wings.
