Odonata Checklist for Sg Durian, Lintang, Perak - IV

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.

Drepanosticta sharpi

Drepanosticta quadrata, D. fontinalis and D. sharpi look alike to each other, and only close inspection on anal appendages could tell them apart. Below photo shows a male of D. sharpi.

Lestes dorothea

Lestes dorothea is definitely a rare damselfly species in Peninsular Malaysia.

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.

Ceriagrion fallax

Ceriagrion fallax is a highland damselfly species. Sporadically, they are found in lowland.

Vestalis luctuosa

I went to Java for Odonata last week. For me, Vestalis is always a metallic green body beautiful odonate. But, my witness of Vestalis luctousa in Java has changed my mind - Vestalis species are not just beautiful but they are highly elegant!

Podolestes orientalis - In Wheel

I spotted a mating pair of Podolestes orientalis.

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.
