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 ...
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 ...
The pedipalps generally consist of an immobile "hand" and mobile "finger", the latter controlled by an adductor muscle. Members of the clade Iocheirata, which contains the majority of pseudoscorpions, are venomous , with a venom gland and duct usually located in the mobile finger; the venom is used to immobilize the pseudoscorpion's prey.
hook-like, as in the mouthparts of many fly larvae. (also uncinate) uncinate hook-like, as in the mouthparts of many fly larvae. (also uncate) unguis (plural ungues) the claws at the tip of most insect pretarsi. urite a segment or part of the abdomen in insects. urogomphus (plural urogomphi) paired "horns" at the posterior tip of the abdomen of ...
In most insect legs, including the posterior four legs of a mantis, the coxa and trochanter combine as an inconspicuous base of the leg; in the raptorial legs, however, the coxa and trochanter combine to form a segment about as long as the femur, which is a spiky part of the grasping apparatus (see illustration). Located at the base of the ...
The jumping spider Phidippus audax.The basal parts of the chelicerae are the two iridescent green mouthparts. The chelicerae (/ k ə ˈ l ɪ s ər iː /) are the mouthparts of the subphylum Chelicerata, an arthropod group that includes arachnids, horseshoe crabs, and sea spiders.
The front pair of legs are modified for use as antennae-like feelers, with many fine segments giving the appearance of a "whip". When a suitable prey is located with the antenniform legs, the amblypygid seizes its victim with large spines on the grasping pedipalps, impaling and immobilizing the prey. This is typically done while climbing the ...
