Earwigs make up the insect order Dermaptera.With about 2,000 species [1] in 12 families, they are one of the smaller insect orders. Earwigs have characteristic cerci, a pair of forceps-like pincers on their abdomen, and membranous wings folded underneath short, rarely used forewings, hence the scientific order name, "skin wings".
Minuca pugnax, like other members of the family Ocypodidae, have chelae of different sizes: a large left chela and a small right chela. A chela (/ ˈ k iː l ə /) – also called a claw, nipper, or pincer – is a pincer-shaped organ at the end of certain limbs of some arthropods. [1] The name comes from Ancient Greek χηλή, through Neo ...
The insect order Zoraptera, commonly known as angel insects, contains small and soft bodied insects with two forms: winged with wings sheddable as in termites, dark and with eyes (compound) and ocelli (simple); or wingless, pale and without eyes or ocelli. They have a characteristic nine-segmented beaded (moniliform) antenna.
They are small arachnids with a flat, pear-shaped body, and pincer-like pedipalps that resemble those of scorpions. They usually range from 2 to 8 mm (0.08 to 0.31 in) in length. [3] The largest known species is Garypus titanius of Ascension Island [4] at up to 12 mm (0.5 in). [5] [6] Range is generally smaller at an average of 3 mm (0.1 in). [2]
The wings of Lepidoptera are minutely scaled, which gives the name to this order; the name Lepidoptera was coined in 1735 by Carl Linnaeus for the group of "insects with four scaly wings". It is derived from Ancient Greek lepis (λεπίς) meaning "(fish) scale" (and related to lepein "to peel") and pteron (πτερόν) meaning "wing".
Japygidae: possess forceps-like cerci (resembling those of an earwig). Usually very aggressive predatory diplurans, using their pincer-like cerci to capture prey, including springtails, isopods, small myriapods, insect larvae, and even other diplurans. [3] Projapygidae: possess stout, short, and rigid cerci. [14]
The dustywings, Coniopterygidae, are a family of Pterygota (winged insects) of the net-winged insect order ().About 460 living species are known. [1] These tiny insects can usually be determined to genus with a hand lens according to their wing venation, but to distinguish species, examination of the genitals by microscope is usually necessary.
They are known to inhabit cold temperate forests to glaciers and the edges of ice sheets. Their optimal living temperature is between 1–4 °C (34–39 °F). They can be killed at colder temperatures due to ice formation in the body, so when the temperature drops below their optimal range they survive by living under snow pack near the soil. [8]
