Here's another shot of the Emperor dragonfly. Again, this was taken at College lake nature centre.

Biology
Dragonflies undergo a type of development known as incomplete metamorphosis in which the aquatic larvae (sometime called nymphs) undergo a series of moults; the stages between moults are known as instars or 'stadia'. After hatching from eggs, the larvae develop quickly through the summer; they enter their final instar during the autumn of the following year, and then enter 'diapause', a form of hibernation, before emerging as adults early the next summer. In the first few instars, the larvae swim by undulating the body from side-to-side; later on they develop a system of jet-propulsion which enables them to easily escape from predators such as water bugs, fish, other dragonfly larvae and beetles. The larvae of the emperor dragonfly are themselves voracious predators, armed with fearsome mouthparts known as a 'mask'; the mask is normally tucked under the head, but is rapidly extended in under 25 milliseconds, piercing prey as large as small fish.

After diapause, final instar larvae leave the water and crawl up vegetation. The adult emerges, leaving the discarded skin of the nymph attached to the plant. The new adults undergo a period of feeding and maturation before starting to reproduce. Males set up territories, which they defend fiercely against other males; they fly rapidly at two to six meters over the water, and very rarely come to a rest. During mating, males and females form a typical 'wheel' mating posture, in which the male grabs the female behind her head using the claspers at the tip of his abdomen. After mating the female lays her eggs in floating vegetation, keeping low to avoid encounters with territorial males.

Threats
This species is not threatened at present, however many dragonflies are vulnerable to water pollution and loss of habitat by infilling of ponds, and drainage of water bodies.

Conservation
The profile of dragonflies has been raised in recent years, and many landowners build ponds in order to encourage them. The British Dragonfly Society aims 'to promote and encourage the study and conservation of dragonflies and their natural habitats, especially in the United Kingdom'.
Here is a link to a previous post of this Dragonfly.

Thanks for looking.

I may not be on TN much over the next couple of weeks. I have a few Football matches to attend. Also next week, I'm sadly going to be another year older!! so a relaxing trip away somewhere sunny is needed.

Very good shot of this Emperor. Well done.

Hi Alan!

This is ultimate trophy for all Odonata fans ;-) Nice composition, very good pose and quality.
Happy birthday Alan! And have a good trip!
What football matches by the way?

Happy Birthday Alan! I'll be leaving for Germany, Austria and Hungary today so I won't be here either! Be sure and check Fisher's contribution to the pecker category! ;^)

Another great post from you, TFS!

Alli

Wow, not only am I impressed with the picture, but also with the very useful information you provided. I currently have several larvae in my pond, a couple of which crawled indeed up on plants in my pond and then came out as adults. I had no idea actually that they'd already been in the pond for a year!
