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 ...
Mecoptera (from the Greek: mecos = "long", ptera = "wings") is an order of insects in the superorder Holometabola with about six hundred species in nine families worldwide. . Mecopterans are sometimes called scorpionflies after their largest family, Panorpidae, in which the males have enlarged genitals raised over the body that look similar to the stingers of scorpions, and long beaklike
Australian water scorpions have six legs; the front two forelegs are pincer-like used for grasping aquatic prey and the hind legs are used for moving about. [3] They have a relatively short, pointed head and small eyes. [2] They have antennae with 3 segments and a finder-like projection, hidden in a groove beneath the eyes. [2]
Griswold et al. stated that the claws may have a significant function in capturing prey. Similar to the Nelson cave spider of New Zealand (Spelungula cavernicola, a gradungulid), Trogloraptor probably dangle upside down from their webs, snatching at passing flying insects with their claws. [8] However their exact prey remains unknown. Captured ...
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]
Pincer-like chelicerae then work to grind and chew the prey prior to ingestion. The tailless whip scorpion may go for over a month in which no food is eaten. Often this is due to pre-molt. Due to the lack of venom the tailless whip scorpion is very nervous in temperament, retreating away if any dangerous threat is sensed by the animal.
They were initially leg-like, then progressed into a more pincer or claw-like shape, as seen today, and restricted to horizontal movement. [1] The forcipules of modern Scutigeromorphs are the most significantly different in shape: they are more leg-like, and cannot hold prey like they are used among other orders: they are used for envenomation ...
