The blue dasher (Pachydiplax longipennis) is an insect of the skimmer family. It is the only species in the genus Pachydiplax. It is widely distributed throughout North America and into the Bahamas. [2] Although the species name longipennis means "long wings", their wings are not substantially longer than those of related species.
Dragonfly returns to same perch each time it darts out to catch very small flying prey. The mating system of dragonflies is complex, and they are among the few insect groups that have a system of indirect sperm transfer along with sperm storage, delayed fertilisation, and sperm competition. [44]
Clubtails are fast-flying dragonflies with short flight seasons. They spend much time at rest, perching in a suitable position to dart forth to prey on flying insects. They tend to perch on the ground or on leaves with the abdomen sloping up and its tip curling down a little. Larger species may perch with a drooping abdomen or lie flat on a leaf.
Clap and fling, or the Weis-Fogh mechanism, discovered by the Danish zoologist Torkel Weis-Fogh, is a lift generation method utilized during small insect flight. [17] As insect sizes become less than 1 mm, viscous forces become dominant and the efficacy of lift generation from an airfoil decreases drastically. Starting from the clap position ...
Calliphora vomitoria, known as the blue bottle fly, [3] orange-bearded blue bottle, [4] or bottlebee, is a species of blow fly, a species in the family Calliphoridae. Calliphora vomitoria is the type species of the genus Calliphora. It is common throughout many continents including Europe, Americas, and Africa.
The Phasmatodea (also known as Phasmida or Phasmatoptera) are an order of insects whose members are variously known as stick insects, stick bugs, walkingsticks, stick animals, or bug sticks. They are also occasionally referred to as Devil's darning needles , although this name is shared by both dragonflies and crane flies. [ 1 ]
Hoverfly nectaring on a small flower bud covered with dew drops. Adult syrphid flies are pollinators. Larvae of many hoverfly species prey upon pest insects, including aphids and leafhoppers, which spread some diseases such as curly top, so they are seen in biocontrol as a natural means of reducing levels
An adult crane fly, resembling an oversized male mosquito, typically has a slender body and long, stilt-like legs that are deciduous, easily coming off the body. [12] [2] Like other insects, their wings are marked with wing interference patterns which vary among species, thus are useful for species identification. [13]
