Wasp stinger, with droplet of venom. A stinger (or sting) is a sharp organ found in various animals (typically insects and other arthropods) capable of injecting venom, usually by piercing the epidermis of another animal. An insect sting is complicated by its introduction of venom, although not all stings are venomous
If a stinger is still embedded, manual removal can reduce further irritation. Washing the affected area with soap and water can help reduce risk of contamination. Oral antihistamines , calamine lotion, topical corticosteroids and cold compresses are common over the counter remedies to reduce itchiness and local inflammation.
The wasps, bees, and ants together make up the suborder (and clade) Apocrita, characterized by a constriction between the first and second abdominal segments called a wasp-waist , also involving the fusion of the first abdominal segment to the thorax. Also, the larvae of all Apocrita lack legs, prolegs, or ocelli.
The Ichneumonidae, also known as ichneumon wasps, ichneumonid wasps, ichneumonids, or Darwin wasps, are a family of parasitoid wasps of the insect order Hymenoptera. They are one of the most diverse groups within the Hymenoptera with roughly 25,000 species described as of 2016 [update] . [ 2 ]
Parasitoid wasps range from some of the smallest species of insects to wasps about an inch long. Most females have a long, sharp ovipositor at the tip of the abdomen, sometimes lacking venom glands, and almost never modified into a sting. [4] Parasitoids can be classified in a variety of ways.
Out of six wasp species, P. exclamans was the only one that occupied artificial nesting sites. [13] It prefers well-lit, open sites.

The smallest wasps are solitary parasitoid wasps in the family Mymaridae, including the world's smallest known insect, with a body length of only 0.139 mm (0.0055 in), and the smallest known flying insect, only 0.15 mm (0.0059 in) long. Wasps have appeared in literature from Classical times, as the eponymous chorus of old men in Aristophanes ...
The DNA of the wasp actually contains portions that are the templates for the components of the viral particles and they are assembled in an organ in the female's abdomen known as the calyx. [14] A 2009 study has traced the origins of these templates to a 100-million-year-old viral infection whose alterations to its host DNA provided the ...
