Larva - Hydrobasileus croceus

The larva of Hydrobasileus croceus is one the most beautiful libellulid larvae. The spiky posterior is the trademark of H. croceus larva. It is normally found at sub-surface water weed.

Larval Emergence - Zyxomma obtusum

Below is a series of pictures showing the larval emergence of a female Zyxomma obtusum.

Orthetrum chrysis vs Orthetrum testaceum - In Wheel

I was so lucky today to see Orthetrum chrysis and O. testaceum in wheel. The more important thing is that I managed to get good shots on them in wheel.....

I have a better picture of Neurothemis fluctuans in wheel. Click here to see the previous entry showing N. fluctuans in wheel.

Obeliks Posture

Dragonflies particularly from the family Libellulidae like to display obeliks posture during hot sunny day. The abdomen is raised to point to the sun in order to minimize the body surface exposed to sun directly from overheating. The obeliks posture is particular beautiful for photography shooting...........

Larva of Podolestes orientalis

The paper of the description of Podolestes orientalis larva has finally been out. Please let me know if you need the soft copy of the paper.

Choong, C.Y. and Orr, A.G. 2010. The larva of Podolestes orientalis from West Malaysia, with notes on its habitat and biology (Odonata: Megapogrionidae). International Journal of Odonatology 13(1): 109-117.

The abstract of the above article is as below:
The larva of the south-east Asian megapodagrionid, Podolestes orientalis, is described and figured. Specimens were collected from shallow forest pools lined with large dead leaves in secondary lowland forest. Final and earlier stadium larvae were found concentrated around the edges of pools in very shallow water. Larvae sometimes perched in exposed situations, just below the water surface, with abdomen upturned and caudal lamellae splayed outward to expose the broad respiratory surfaces. This represents the first account of the immature stages for this south-east Asian genus. The caudal lamellae are very broad and flattened, inserted horizontally, suggesting a close relationship between the genus Podolestes and Australian region megapodagrionids.


So, how does the larva of P. orientalis look like? Here you go......




Below are two photos taken in situ at the natural habitat of P. orientalis larva.


So, how does the natural aquatic habitat look like for the larva of P. orientalis? The below photo shows the aquatic habitat from where I found the larvae of P. orientalis. The larvae concentrated at the shallow water edge covered with fallen leaves and sticks......

A Worn Dragonfly

I was observing odonates in a late afternoon and I bumped into this female Trithemis aurora...... I felt sad to see the pathetic condition of this female T. aurora, it looks like she is an old and worn lady....... it must be the aggressiveness of many males to make her like this........ Well, after a while I cheered up thinking that she would be contented as she has experienced the best part of her life!

Larval Emergence - Pseudagrion rubriceps

I showed the grassy drain/streamlet in an earlier entry. The site is a good habitat for Pseudagrion rubriceps. I found hundreds and thousands of Pseudagrion rubriceps larvae in the grassy drain/streamlet. The larvae like to cling on the roots of the plants at the water edge. I managed to record the larva emergence of P. rubriceps..........
