This generally produces less power and is less efficient than asynchronous muscle, which accounts for the independent evolution of asynchronous flight muscles in several separate insect clades. [3] Insects that beat their wings more rapidly, such as the bumblebee, use asynchronous muscle; this is a type of muscle that contracts more than once ...
Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly. They are found on the second and third thoracic segments (the mesothorax and metathorax ), and the two pairs are often referred to as the forewings and hindwings , respectively, though a few insects lack hindwings, even rudiments.
Her first book, Insects Are Just Like You And Me Except Some Of Them Have Wings was published by Blaft Publications in 2008. The Guardian named the book as one of the best independently published ebooks in the weird fiction genre, calling it "just very, very beautiful."
There are two basic aerodynamic models of insect flight. Most insects use a method that creates a spiralling leading edge vortex. [19] [20] Some very small insects use the fling-and-clap or Weis-Fogh mechanism in which the wings clap together above the insect's body and then fling apart. As they fling open, the air gets sucked in and creates a ...
Mayflies are delicate-looking insects with one or two pairs of membranous, triangular wings, which are extensively covered with veins. At rest, the wings are held upright, like those of a butterfly. The hind wings are much smaller than the forewings and may be vestigial or absent.
The vestigial rear wings of flies and crane flies are used for navigation, and arguably the most accomplished insect aviator is the hoverfly, which makes continuous adjustments while in the air to remain stationary. Beetles that are capable of flight have to keep their wings below covers, and a specimen of the largest, the titan beetle, is ...
Several ancient civilizations considered the insect to have supernatural powers; for the Greeks, it had the ability to show lost travelers the way home; in the Ancient Egyptian Book of the Dead the "bird-fly" is a minor god that leads the souls of the dead to the underworld; in a list of 9th-century BC Nineveh grasshoppers (buru), the mantis is ...
Dragonflies (suborder Anisoptera) are heavy-bodied, strong-flying insects that hold their wings horizontally both in flight and at rest. By contrast, damselflies (suborder Zygoptera) have slender bodies and fly more weakly; most species fold their wings over the abdomen when stationary, and the eyes are well separated on the sides of the head.
