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
A scorpion sting is an injury caused by the stinger of a scorpion resulting in the medical condition known as scorpionism, which may vary in severity. The anatomical part of the scorpion that delivers the sting is called a "telson". In typical cases, scorpion stings usually result in pain, paresthesia, and variable swelling.
The male has a pair of claspers at the end of its tail (for holding the female during mating), [6] giving it a scorpion-like appearance, [6] although it is not a stinger. The adult insect has a wingspan of about 35 millimetres (1.4 in), [ 6 ] with wings that are mostly clear, but have many dark spots or patches.

In the region of South Africa, the deadliest scorpion belongs to the Tityus genus. In India and Mexico, the deadliest scorpions involved in scorpionism are Mesobuthus and Centruroides, respectively. [2] In Central America, most scorpion stings are mildly toxic to humans, however, Panama has reported an incidence of 52 cases per 100,000 people ...
Panorpa is a genus of scorpion-flies that is widely dispersed, especially in the Northern Hemisphere. However, they do not occur in western North America. Thirteen species occur in eastern Canada. [3] About 260 species are described as of 2018. Larvae and adults feed on carrion. [4]
Tityustoxin-1, TsTX-I is the most toxic protein among the neurotoxins in this venom, with an intravenous and intracisternal LD 50 (mouse) of 76 ± 9 and 1.1 ± 0.3 μg/kg, respectively. The identification of TsTX-I as a potent component of T. serrulatus venom characterized it as the major and main neurotoxin from this venom. [ 1 ]
The deathstalker is one of the most dangerous species of scorpions. [10] [11] Its venom is a powerful mixture of neurotoxins, with a low lethal dose. [12]While a sting from this scorpion is extraordinarily painful, it normally would not kill a healthy adult human.
