|Yesterday I posted the Male Banded Demoiselle this is the female she is a metalic Green instead of his blue colour.The wings too are different sort of a metalic allover bronze colour, in fact they look like 2 different species. The hairs on both their legs are used to help catch the prey insects mainly thing like gnats, alderflies , caddis and even mayflies with are almost as big.They do this by holding them out in front and the hairs make the mesh of a very effective net from which it reaches down with its head and grabs the catch and either eats it on the wing or finds a quiet perch on which to eat the prey. Its amazing how fast they can chew-up a victim.|
When the nymphe emerges from the water the to transform into the adult, they can travel upto 300ft/100m away from the water to find a suitable shrub in which to transform. once she can fly , she will leave the area to feed up and become sexually mature.The female will arrive back at the river Between 10.00am and 2.00pm to find the males waiting to display to her. if she likes what she see`s, she will land next to him on the site he has picked out for her to lay in.he will fly up and land on her wings and climb down till he can grasp her behind the head , they will the go into the normal dragonfly wheeled position and they will mate for all of 90 seconds. not quiet the fastest but a close run thing.She will part from him and begin laying eggs imeadiatly into the plant material they matted on, eggs are inserted below waterlevel in cuts made into the stem with her ovipositor, she can be doing this fully submerged beathing on the air trapped between her wings , if she isnt eaten by some thing like a hungry fish shee can carry on laying for 45 mins. at an average of 1 every 6sec. thats a lot of eggs.
The eggs take 14 days to hatch then spend 2 years in the nymph form before emerging to start the cycle again.

Nice one Rob, lots of details in the wings, I like the criss cross of the reeds too. I see your one has lost a little detail from the head too. They obviously don't like having their photos taken.

A very good macro shot.
Efficient composition and DOF, lovely colors and details...
No doubt, a great one!
Great shot Robert - as well as the male-shot. The colours are great and again you managed to get a lot of details. I espceally like the reflection in her wings which seem without scatches at all, so I guess that she is not very old.

Well done, Robert. There is wonderful detail here and I know that is not easy...Damselflies are quite small in comparison to dragonflies. Also getting that kind of focus when you have green on green is not an easy feat either.
