Coeliccia kimurai

I was thrilled to record the presence of Coeliccia kimurai somewhere in Perak. The type spciemens (two specimens) were from southern of Thai Peninsula (Yala Provine) collected on July 26, 1988 by Y. Kimura. Asahina described the species after Kimura in 1990. Since then C. kimurai has not been spotted until May 2007 when two male specimens were caught somewhere in Negeri Sembilan. Now, this is the third location (somewhere in Perak) where C. kimurai has been recorded. Three male speciemens were caught in the third location. Showing below is one of the speciemens being caught in the thrid location.

Newly Emerged Female Neurothemis fluctuans

I was down into the swampy pond of Bangi Forest Reserve with my camera. I spotted a newly emerged female Neurothemsi fluctuans. The adult female was still attached to its exuvia. You may click here to view the male N. fluctuans and the newly emerged male adult.

Emerging Ceriagrion chaoi

I managed to take a series of photos showing the larval emergence of Ceriagrion chaoi.

Larval Emergence - Neurothemis fluctuans

I caught some small size libellulid larvae a week ago and am breeding them in small aquarium. One of the larvae emerged yesterday. It appeared to be a male Neurothemis fluctuans. Neurothemis fluctuans is one of the most common dragonfly species in Peninsular Malaysia. The male has red colour wings and body while the female is in yellowish brown colour.

Libellulidae - Urothemis signata

Urothemis signata is a medium-sized red dragonfly species. However, it is not too difficult to differentiate U. signata from other medium-sized red dragonfly by having open wing venation. The base of hindwings have dark patches. Urothemis signata just likes to play around under the hot sun!

Emerging Agrionoptera insignis

I recorded the process of emergence of Agrionoptera insignis. The whole process took roughly 90 minutes occurring during night time.

Finally It emerged..........

I posted an entry on March 25, 2009 mentioning a larva I caught in Bangi Forest Reserve. I bred it in an aqaurium, and it finally emerged last night! Now, I have the answer for the identity of the larva................. it is Zyxomma petiolatum.

I caught many larvae of Agrionoptera insignis from forest of Pangkor Island last week. I'm breeding them in aquarium. One of the larvae emerged last night. I managed to snap a few shots of it.

Coenagrionidae - Amphicnemis gracilis

Amphicnemis gracilis is not a common damselfly species. I only bumped into it a couple of times during my past five years of odonate samplings. Amphicnemis gracilis is strictly restricted to swamp habitat. The male adult has metalic dark green body. However, the immatured female adult looks more elegant with stricking red body.

Agrionoptera insignis is an elegant dragonfly species. It is normally found at swampy area. I bumped into it during my recent visit to Pangkor Island. The appearence of A. insignis resembles A. sexlineata and Lathrecista asiatica.

Coenagrionidae - Pseudagrion microcephalum

I spotted this Pseudagrion microcephalum couple at an exposed grassy pond adjacent to Bangi Forest Reserve in a late afternoon. Pseudagrion microcephalum normally flies low at the surface of the water. Its blue marking (for male adult) is quite striking. However, female adult has olive green mixed with a bit blue marking.
