A more complicated form of epigyne is found in spiders of the genus Araneus, where there is developed an appendage which is usually soft and flexible, and which is termed the scape or ovipositor. When there is a well-developed scape, the tip of it is usually more or less spoon-shaped.

What animals have Ovipositors?

The stingers of the Aculeata (wasps, hornets, bees, and ants) are ovipositors, highly modified and with associated venom glands. They are used to paralyze prey, or as defensive weapons. The penetrating sting plus venom allows the wasp to lay eggs with less risk of injury from the host.

Do all insects have Ovipositors?

Most female insects have an egg-laying tube, or ovipositor; it is absent in termites, parasitic lice, many Plecoptera, and most Ephemeroptera.
