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.
Horntail or wood wasp are any of the 150 non-social species of the hymenopteran family Siricidae, a type of wood-eating sawfly.The common name "horntail" derives from the stout, spine-like structure at the end of the adult's abdomen which is present in both sexes.

An insect sting is complicated by its introduction of venom, although not all stings are venomous
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 ]
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.
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.
Like most of the Chrysidoidea, the Bethylidae are stinging Hymenoptera and most are parasitoids. Some of them, however, have developed their parasitoidal biology along predatory lines and they sting and malaxate their victims into paralysis.
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 ...
