Friends,


While watering my plant this morning I found these two damselfly enjoying themself. I returned home late in the morning from the hospital after giving blood to one of my friend who is suffering from Dengue. But after looking this I then immediately went inside and tookout my camera and clicked. The two shots were taken in different locations. The lighting was little poor as the shot was taken at 630 in the morning. Today it was windy and slightly chilly. I tried to collect the information on them this time little detailed. If they are not correct my apologies and do correct me. Thanks for visiting.

Information on the first one
============================

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Odonata
Suborder: Zygoptera
Family: Coenagrionidae
Genus: Ischnur
Species: I. aurora

Aurora Bluetail Damselflies are tiny damselflies. Males are beautifully have the colours of the rainbow. The head and thorax are from green to yellow, the abdomen is from yellow to orange to red. There is the bright blue at the tip. The back of the thorax is black. The females are pale grey in colour. There is a slight noise on the first shot as I had to use a little higher ISO value to shoot to get the light.

Information on the 2nd One.
===========================

Pygmy Dartlet - Agriocnemis pygmaea - Male

This smallest damselflies in Malaysia is also the smallest in the world . Hind wing is 11 mm. Abdoment Length is 20mm
The male damselfly's head and thorax is pale green in color with black pattern. Abdomen is pale red with black with the red tail light.

They are not easy to find for they are very small in size. They usually hide low and near the water edge, among thick grasses. They fly slow and float like a moth from one grass to another less than a foot away.

These two families of Agriocnemis pygmaea and Agriocnemis femina oryzae always live in the same territories. Because they mingle so close to each other very often the young male of both are mistaken as the other. Damselflies are beneficial predators because they consume large quantities of insects such as flies, mosquitoes and moths and some eat beetles and caterpillars.

sexual Practice
===============

The male curves his abdomen to clasp her prothorax with his anal appendages to form the tandem pair. The male does this clasp less than a second.

The tandem position remained for about 10 minutes during which they flew together from one grass to another to stay away from my camera.

This heart shape wheel is known as Wheel Position. (In dragonfly the tandem is holding the back of head.)

All males have their genital opening for sperm at the ninth abdominal segment. Beside the first genitalia male Damselflies have a secondary genitalia on the second abdominal.

Before copulation, sperm is moved from the first genitalia (Section 9) into the secondary genitalia (section 2). This is done by The bending the abdomen forward for the first genitalia to touches the secondary genitalia. This take few seconds.

When the sperm in the male secondary genitalia is ready, the pair forming a tandem by male holding by female's neck (prothorax). The female bend up her abdomen to the of the male's genitalia and form the wheel position. The female's abdomen contact with male's secondary genitalia to receive sperm.

The male curves his abdomen to clasp her prothorax.
Noteice that for damselflies the clasping is on the prothorex. But for dragonflies the clasping is on the back of the head.

Hola Ganesh.- Muy buen trabajo para presentar a esta Libelula de bellos colores. Exelente y fino trabajo.
Luis52.

Though the images are not needle sharp, they are still well captured in the existing light conditions, Ganesan.
Both the species of damselflies are quite attractive and look beautiful in this dual image collage.
TFS and regards.
