An Ovipositor is an organ at the end of the abdomen of female insects and it is used for laying eggs.
They are often tubular or blade-like in shape, so that the eggs can be inserted into the ground, plants or other animals.
In some insects the ovipositor is modified to form a sting.
The image on the right shows a female from the genus Megarhyssa, which contains large species of ichneumon wasps. Some of these species are known for having the longest ovipositors of any insect.
