Dragonflying at Denai Sungai Kebangsaan @ JPS Hulu Langat

I did an Odonata survey along Denai Sungai Kebangsaan @ JPS Hulu Langat (or known as Denai Sungai Langat) in Bandar Baru Seksyen 3, Selangor (Figure 1) on 11 April 2026, from10 am to 1 pm. The Denai is easily accessed by Persairan Universiti, the road from Bandar Baru Bangi heading to the main entrance of Universiti Kebangsaan Malaysia. The length of the whole Denai (from point A to point B; Figure 1) is roughly 3 km, and it is facilitated by tarred walkway (actually it is a cycling track). The walkway is just along the river bank. The start point of the Denai (point A; Figure 2; 2°55'35"N 101°46'32"E) is next to Persairan Universiti. A small parking space is available at the start point of the Denai (Figure 2). Point A oversees the pond at Bandar Baru Bangi Seksyen 3.The end of the Denai is a dead end (point B; see Figure 3; 2°57'10"N 101°47'6"). A nice open marsh (point C; Figure 4; 2°56'10"N 101°46'50"E) is located about 600 m from the start point, and it is a nice spot to watch dragonflies. A few chairs and a hut are erected along the walkway for visitors (Figures 7 & 8). Fishing enthusiasts frequent the Denai to fish at Sungai Langat. The Denai is also frequented by cyclists. In the 3-hour of survey, I manage to spot 14 species Odonata species, 1 was damselfly and 13 were dragonflies. Most of the odonates were spotted at the marsh (point C).  

Here are the Odonata species spotted during the field survey along the Denai on 11 April 2026

Dragonflying at Bandar Baru Bangi Seksyen 3

I did an Odonata survey at a pond in Bandar Baru Seksyen 3, Selangor (GPS coordinate: 2°56'0"N 101°46'28") on 4 April 2026, from 10 am to 1 pm. The weather was good during the field survey. The pond is located next to Sungai Langat, and it is easily accessed by Persairan Universiti, the road from Bandar Baru Bangi heading to the main entrance of Universiti Kebangsaan Malaysia (Figure 1). The pond is well vegetated with one side faced by the beautiful residence houses (Figure 2). Another corner of the pond faces Persiaran Universiti (Figure 3). Basically, you are able to view one corner of the pond from Persiaran Universiti (on the traffic from Bandar Baru Bangi to Universiti Kebangsaan Malaysia main entrance). The pond is frequented by visitors for fishing (Figure 4). Next to the pond is a spacious parking are (Figure 5). Walking down from the parking area is kid playground (Figure 6). Walking further from the kid playground is the beautiful pond. I manage to spot 12 species Odonata species, 3 were damselflies and 9 were dragonflies. Brachythemis contaminata, Crocothemis servilia and Acisoma panorpoides were spotted in abundance during the field survey.

Dragonflying at Sungai Durian, Lintang, Perak

Sungai Durian flows through Kampung Sungai Durian, Lintang, Perak. The Perak state government develops an ecotourism project at Kampung Sungai Durian - Lata Gerik Kampung Sungai Durian. One of the attractions to Lata Gerik Kampung Sungai Durian is the Sungai Durian (see the photos below). The water of the stream is clean. I visited to Lata Gerik Kampung Sungai Durian on 19 February 2026 to survey the Odonata. I managed to record 26 species of Odonota (11 species are damselflies and 15 species are dragonflies) at Lata Gerik Kampung Sungai Durian (see the species list below).

A total of nine species of Odonata were recorded - one was damselflies and eight were dragonflies. They were just very common pond species.

Scientific Expedition of Melaka Forests

I joined the Scientific Expedition of Melaka Forest 2025 organized by Jabatan Perhutanan Negeri Melaka and Jabatan Perhutanan Semenanjung Malaysia on 22-26 June 2025. The expedition covered three forest reserves - Hutan Simpan Bukit Sedanan, Hutan Simpan Bukit Senggeh and Hutan Simpan Batang Melaka. The basecamp of the expedition was located at Taman Negeri Melaka Bukit Sedanan.

Scientific Expedition to the Royal Tiger Reserve, Pahang

It was a privilege for me to join the Scientific Expedition of Al-Sultan Abdullah Royal Tiger Reserve in the state of Pahang on 10-16 May 2025. The expedition was organized by Perbadanan Taman Negeri Pahang in cooperation with Enggang Management Service. The expedition was joined by over 30 researchers for various institutions. The expedition was assisted by local field guides and boatmen from Kampung Bukit Mat Daling.

We were at the jetty of Kampung Bukit Mat Daling, setting off to the base camp in the Tiger Reserve. The boat journey from the jetty to the base camp took almost 2 hours on Sungai Tembeling.

Travelling at boat along Sungai Tembeling to the base camp in the Tiger Reserve was exciting and fun.

The base camp was located by Sungai Tembeling at Kuala Sungai Lurut.
