Size
An adult has a wingspan of 44mm. Approximate overall length - 36mm.
Behaviour
The males are often aggressive and will see off intruders. This damselfly has a habit of remaining concealed and only taking short flights. Damselflies eat small insects and small aquatic invertebrates. The Large Red Damselfly is not very active and prefers to spend most of its time flying around its territory and settling on vegetation around ponds - streams and and slow moving water
Habitat
This Damselfly can be found on many different types of water-body from small ponds and lodges to ditches, canals and rivers and streams. The Large Red Damselfly chooses small standing water, preferably with a rich vegetation, both in the water as on the waterfront.
Breeding
During mating the male clasps the female by her neck while she bends her body around to his reproductive organs – the shape is often called a mating wheel. The pair fly together over the water. Their eggs are laid within a suitable plant, just below the surface and hatch. The aquatic larvae take two years to complete development. The larvae - called nymphs live in the water. Metamorphosis then occurs and the adult insect expands and dries its wings before flying off. There is no pupal stage in the development of dragonflies and damselflies. Nymphs eventually climb out of the water - climbing up a stem to emerge from their split skins as damselflies.
Distinguish a Dragonfly from a Damselfly
I wondered what makes this insect a damselfly as opposed to a dragonfly and have ascertained that dragonflies are distinguished from Damselflies by their more robust appearance, and powerful flight. Dragonflies wings are held at right angles to the body when at rest and the eyes in most species of dragonflies actually touch
Damselflies are smaller in size than dragonflies and usually have a weaker and briefer flight. When resting their wings are usually held together over their back. Damselflies eyes are separated instead of touching as in the dragonflies.
Mating Dragonflies
If you see the shape of the two bodies looking like a a heart or a wheel - then these are two dragonflies mating. The male grabs the female just behind the head. The female holds on to the male just behind the body. The male is then impregnating her. This is actually very strange as the male's sex organs are actually at the end of his tail. So if the end of the females body is just behind his own body and not near the end of his tail, how does he do it? After producing his sperm, he transports it to a special save-keeping organ near the front of the tail. And that's exactly where the female grabs him! When she is depositing her eggs the males of many species hold their grip on the female, to prevent other males from breaking in and taking over.
