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.
Like dragonflies, they reproduce using indirect insemination and delayed fertilisation. A mating pair form a shape known as a "heart" or "wheel", the male clasping the female at the back of the head, the female curling her abdomen down to pick up sperm from secondary genitalia at the base of the male's abdomen.

Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly.They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments.
The Cordulegastridae are a family of Odonata (dragonflies) from the suborder Anisoptera. They are commonly known as spiketails. [2] Some vernacular names for the species of this family are biddie and flying adder. [3] They have large, brown or black bodies with yellow markings, and narrow unpatterned wings.
As for why so many dragonflies end up in Milwaukee, eastward winds push the dragonflies toward Lake Michigan during their migration, Jackson said. However, the insects will typically avoid flying ...
Like all other species of dragonfly, the larvae of this species grow by moulting (in which the exoskeleton is shed) several times during development. [9] In the early stages of development, larvae preferentially inhabit sphagnum moss , which may provide a reliable source of food because the moss can trap organic matter that would otherwise sink ...
Epiophlebia laidlawi, the Himalayan relict dragonfly, is one of four species of Epiprocta in the family Epiophlebiidae.They have at one time been classified as a suborder Anisozygoptera, considered as intermediate between the dragonflies and the damselflies, partly because the hind wings and fore wings are very similar in size and shape, and partly because the insect at rest holds them back ...
