Latest Insect wing Stories
One of the many reasons why hummingbirds are so enchanting is the mystery of how they are able to move as they do, hovering near flowers as they consume nectar before darting with incredible speed to the next plant.
LAFAYETTE, La., Oct. 30, 2014 /PRNewswire/ -- ARC Group, Inc.
A well-known biologist once theorized that many roads led to Rome when it comes to two distantly related organisms evolving a similar trait.
How did the earliest birds take wing? Did they fall from trees and learn to flap their forelimbs to avoid crashing? Or did they run along the ground and pump their “arms” to get aloft?
Researchers from North Carolina State University have developed a way to convert moths into miniature drones by electronically manipulating their flight muscles and monitoring the signals the insects use to control them.
Yale University scientists have chosen the most fleeting of mediums for their groundbreaking work on biomimicry: They've changed the color of butterfly wings.
Hummingbird wings are more efficient than even the highest-quality helicopter blades when it comes to generating lift, according to new research appearing in the current issue of the Journal of the Royal Society: Interface.
The social insects, including bees, wasps, ants and termites have developed a highly advanced society where division of labor amongst workers to serve the queen's reproduction has long fascinated biologists who have wanted to uncover the molecular pathways driving the complex behavior of insect societies.
A new study of the colorful "eyespots" on the wings of some butterfly species is helping to address fundamental questions about evolution that are conceptually similar to the quandary Aristotle wrestled with about 330 B.C. – "which came first, the chicken or the egg?"
High food stress may impact wing size and coloration—both indicators of migratory success—in monarch butterflies
The Darwin termite (Mastotermes darwiniensis), also known as the giant northern termite, is a species of termite that can only be found in northern areas of Australia. This species is the only member of its genus and the only living member of the family Mastotermitidae. It does not typically occur in large groups, but if food, water, and space are adequate, populations can number in the millions. This typically occurs in areas where natural conditions have been altered including near piles of...
The dot-winged baskettail (Epitheca petechialis) is a species of dragonfly that can be found in the United States, with a range that includes Texas, Oklahoma, and Colorado. It can be seen later in the year than other baskettail dragonflies, typically between the months of January and July. The species is named for its spots, although not all individuals hold these spots, which occur on the hind wing. It is difficult to distinguish individuals with no spots from other baskettail dragonflies,...
The common baskettail (Epitheca cynosure) is a species of dragonfly that can be found in North America. The scientific name cynosure is thought to mean dog tail, because of the tendency of the appendage on the end of the abdomen to wave around like the tail of a dog. Its thorax is hairy and brown in color and some individuals hold a triangular marking at the base of the hind wing. This species is typically seen between the months of January to August, but can be seen between October and...
Rhithrogena germanica, known as the March brown mayfly in in the British Isle, is a species of mayfly that can be found throughout northern and central areas of Europe. Its range includes the River Tweed in England, Hesse in Germany, Denmark, Poland, and France. It was first described by Alfred Edwin Eaton, who studied a male specimen from the River Rhine. Rhithrogena germanica begins its lifecycle in the larval stage, as a water dwelling naiad that is typically found in fast flowing,...
