 Males also have secondary genitalia (including the anterior lamina, hamuli and posterior lamina) on S2 and S3.Female damselflies and some dragonflies have a strong ovipositor on the underside of S8 and S9, but in many dragonflies the egg-laying apparatus is merely a spout, a basket, or a pair of flaps.Some species have foliations (leaf-like extensions) on S8 and/or S9.
