| | Ovipositor - Wikipedia, the free encyclopedia |
 | | The sting of wasps, hornets and bees is also an ovipositor, in this case highly modified and associated with poison glands. | | | These species are parasitic in the larval stage on the larvae of wood-boring insects, hence the egg must be deposited in the burrow of the host. | | | None of these examples is quite as remarkable as the Megarhyssa species of Ichneumon wasp (parasitic Hymenoptera), the females of which have a slender ovipositor several inches long, used to drill into the wood of tree trunks. |

| | Ovipositor |
| | The most diverse ovipositor morphology is probably found in the Hymenoptera (bees, wasps and ants). | | | One of the most interesting modifications of the ovipositor is found in stinging Hymenoptera, where the ovipositor is not used to lay eggs at all but is instead modified into a stinger. | | | The morphology of the ovipositor is extremely varied among insects - they may be short or long, thin or thick, blunt or sharp. |

| | Wasps: pictures, information, classification and more |
| | In the vegetarian sawflies, the abdomen is broadly attached to the thorax and the ovipositor is rigid; in the higher wasps, the abdomen is flexibly attached to the thorax and the ovipositor is movable. | | | Most stinging wasps are predators or scavengers; their ovipositors may be modified to inject venom used for killing prey or for defense. | | | Wasps are characterized by two pairs of membranous wings and an ovipositor (tube for laying eggs) that may be modified in various ways. |

| | Queen |
| | Once all eggs were laid the ovipositor became necrotic and fell from the Queen's abdomen. | | | Both the Queen and her ovipositor are suspended from the roof of the hive by thick strands of resin. | | | Once in the ovipositor the eggs will slowly travel through a thick amniotic fluid, which is released and replenished by the Queen's reproductive system. |

| | Microscopy UK / MICSCAPE : Wasp Sting |
| | An ovipositor can be described simply as a complex sheathed tube designed for piercing the ground, plant tissue, or the bodies of other insects or animals, the egg being passed down the inside of the tube and into the host. | | | The stinging mechanism has evolved from the ovipositor which, although used by many other insects for egg-laying, is now redundant for this function in the wasp. | | | A good point to remember is that as the stinging mechanism actually evolved from the female egg-laying organ, it is only the females of wasps and bees which actually sting. |

| | When the ovipositor is fully inserted into the wood it touches a host larva and she then lays an egg through a narrow gap in the ovipositor. | | | Although the ovipositor of the giant ichneumon wasps is quite long, don't let it intimidate you -- these wasps do not have poison glands like other stinging Hymenoptera and they are not inclined to stab you with it either. | | | Each species has a different length ovipositor and can use horntail larvae only at the depth in the wood to which their ovipositor extends. |

| | Ovipositor |
| | The ovipositor is comprised of paired appendages (usually three) which form into a shaft that is used for laying eggs. | | | Depending on the Ichneumon species, venom may also be injected into the host's body along with the eggs in order to prevent the host's immune system from destroying the eggs. | | | Eggs may be deposited in various locations including into or on plant tissue (photo 1), in the ground or even into the bodies of animals. |
