I visited Sg Durian, Lintang, Perak for the forth time yesterday to survey the odonate diversity. I managed to add five more species to the previous checklist. The added five species are Orthetrum glaucum, Orthetrum sabina, Brachydiplax farinosa, Potamarcha congener and Neurothemis fulvia. Now the total number of odonate species recorded from Sg Durian is 41.

Coeliccia didyma
Coeliccia didyma resembles C. albicauda on the thoracic dorsal marking. However, it is distinguished from C. albicauda by havinng blue tail and has larger size. In Peninsular Malaysia, the distribution of C. didyma is more to the northern part.

Waterfalls
I visited to a few waterfalls in Terengganu last month. These waterfalls are just beautiful.

Libellago aurantiaca
From far, Libellago aurantiaca looks alike Sundacypha petiolata. However, a close look reveals that the thoracic yellow marking and dark patch on hindwings are different between these two species.

Exploration of Chamah Highlands
I had the opportunity to join the Exploration of Chamah Highlands organised by Jabatan Perhutanan Kelantan (Kelantan Forestry Department) and Universiti Malaysia Kelantan. The exploration was held on July 24-29, 2011. We all camped at a site with an evelation of 720 m from sea level. I really enjoyed the cool weather at this altitude. I was at Chamah Highlands for Odonata survey.

One of the things that attracted my attention is a plane wreckage at the Chamah Highlands at an evelation of 820 m from sea level. The plane named Royal Dakota was on its way to this remote forest to delivery supplies to the Orang Asli living in this area in 1950. The Royal Dakota carried 12 persons including the pilot - 11 Britons and one Malay. Unfortunately, it clashed due to its engine failure. The Orang Asli burried eight bodies near to the plane wreckage, and the other four persons were still missing. The plane wreckage was only rediscovered in 2008 by army.... the plane wreckage and the burial ground had been sleeping for almost 60 years deep in the forest before being rediscovered by people from outside.

Drepanosticta quadrata - Female
Drepanosticta quadrata is truely a forest species, and it is widespread in Peninsular Malaysia. I have bumped into the male of D. quadrata on many occassions, but spotting a female of D. quadrata is truely not an easy task. Finally, I spotted females of D. quadrata, and now I know why it is so hard to spot female of D. quadrata....

Female - Trithemis aurora vs Trithemis festiva
I was asked some time ago by a visitor to my blog how to tell apart the females of Trithemis aurora from Trithemis festiva. The colouration of males for these two species is so distinct that you still could distinguish them easily without wearing glasses (if your vision is impaired)... hehe. You may click here to view the male T. aurora and here to view the male T. festiva. The marking on the abdomen-thorax of female T. aurora is different from that of the female T. festiva.

Onychothemis testacea
Onychothemis testacea is definitely rare in Peninsular Malaysia. I have so far spotted O. testacea at two locations in Peninsular Malaysia - one at Sg Bebar, Pahang and the other one at Bangi Forest Reserve, Selangor. I photographed a male before (click here to view) some time ago. Now, I finally have a a photo of female O. testacea. The female resembles the male in colouration.

Seremban Lake Garden
I arrived at Klana Resort Hotel, Seremban this late afternoon to attend a seminar. I saw a small lake (Seremban Lake Garden; shown in the photos below) not too far from the hotel. After checking in the hotel, I went to the lake to do Odonata observation for two hours (5-7 pm). The weather was good, and I went around the lake looking for Odonata. I spotted ten species of Odonata. Brachythemis contaminata and Pseudagrion microcephalum were present in abundant at the lake in late afternoon.

Bangi Forest Reserve
Bangi Forest Reserve has a small unnamed river. It is a very nice river for many common Odonata species.
Cratilla metallica
The female Cratilla metallica looks alike the male C. metallica. Below are two photos of female C. metallica. You may view the photos of male C. metallica here.

Kota Damansara Forest Reserve
I was on a scientific expedition at Kota Damansara Forest Reserve (KDFR), Selangor the last couple of days. KDFR is an island logged-over forest sitting in the middle of Kota Damansara township. This 600-ha forest reserve is surrounded by highway and residential areas. Nevertheless, KDFR contains some lakes and small streams which support some Odonata species. Our group (Odonata group) managed to record 48 Odonata species in KDFR.

IUCN Workshop in Laos
I'm back from the IUCN workshop in Vientian, Laos. What a fruitful visit indeed. I met so many regional odonatologists in the workshop. The workshop evaluated freshwater biodiversity of Indo-Myammar, and the evaluation was mainly on aquatic plants, mollucs, fish and dragonflies. The workshop attended by roughly 30 participants of different biodiversity groups, and we had a group photo on the last day of the workshop (photo below).
We were posing on the river bank of Mekong River for the group photo. It is still the dried season in Laos, and the Mekong River is almost dried out.
I was intoxicated every evening in Vientian by this stuff. Of course, I did it with some of the odonatologists!!!! hehehehehehe
