Dragonflies and Damselflies of Central Park Eco Forest Semenyih

Dragonflies and Damselflies of Central Park Eco Forest Semenyih, Selangor

I surveyed the dragonflies and damselflies at Central Park Eco Forest, Semenyih, Selangor on the 25th and 27th August 2026. Central Park Eco Forest is about 500 m from the retention pond next to Eco Forest Gallery. There are two large retention ponds in the park. The ponds are well maintained by the developer. However, the water edges of the ponds are quite bare (very few aquatic vegetation). I spotted 15 Odonata species during the survey, 4 damselflies and 11 dragonflies. I was quite surprised to spot Chalybeothemis chini there. Chalybeothemis chini was found hanging around the aquatic plants (Pandanus plants) at the water edge of one of the ponds. At least 5 individuals were spotted during each time of visiting. They were quite tame at the site and easy to be photographed (click here to see a photograph of Chalybeothemis chini taken at Central Park Eco Forest). Overall, the number of Odonata species recorded at the park was not high, and I believe it is partly due to the bare condition of the water edges of the ponds. Nevertheless, Central Park Eco Forest is still a good site for dragonfly watching at urban landscape.

Dragonflies and Damselflies of Eco Forest Semenyih

Dragonflies and Damselflies of Eco Forest Semenyih, Selangor

I surveyed the dragonflies and damselflies at the retention pond next to Eco Forest Gallery, Semenyih, Selangor on 22 August 2026, from 10.30 am to 1.00 pm. The pond is well maintained by the developer. A beautiful fountain is located at the centre of the pond. I spotted 18 Odonata species during the survey on 22 August 2026, 3 damselflies and 15 dragonflies. The most surprising observation is the presence of Chalybeothemis chini. Chalybeothemis chini was found hanging around the aquatic plants (the part facing the water) next to the hut by the pond (see the last photo with mark area). Other interesting species is Indothemis carnatica. Actually, I visited the pond a couple of times in June and July 2026. 7 species were observed in the precious visits but not spotted on 22 August 2026 - Lestes decipiens, Pseudagrion rubriceps, Diplacodes trivialis, Hydrobasileus croceus, Indothemis limbata, Rhyothemis variegata phyllis and Pantala flavescens. I have to say the retention pond at Eco Forest Gallery is one of the good sites for dragonfly watching at urban landscape.

Dragonflies and Damselflies of Taman Rimba Alam, Putrajaya

Dragonflies and Damselflies of Taman Rimba Alam, Putrajaya

Taman Rimba Alam is an urban forest park located between Precincts 14 and 15 in Putrajaya. It is managed by Perbadanan Putrajaya. I visited Taman Rimba Alam on 18 August 2026 (from 10.15 am to 1.30 pm) to observe Odonata. Taman Rimba Alam is divided into 7 zones. I only observed the Odonata at zone C. Zone C has a beautiful lake/pond (Tasik Meranti). Tasik Meranti consists of three compartments which are inter-connected (see the Google map and photos below). I managed to record 24 Odonata species at Tasik Meranti (see the species below). Actually, Phon (2025) produced a checklist of Odonata for Taman Rimba Alam consisting 29 species. The Odonata data covered the whole Taman Rimba Alam, including Tasik Meranti (zone C), spanning a period from June to November 2024 (a total of 10 sampling days). Phon (2025) listed 15 species from zone C. Three species recorded at zone C by Phon (2025) not observed on my visit are Lathrecista asiatica, Trithemis festiva and Camacinia gigantea. Nevertheless, 5 species were recorded by me not appeared in Phon (2025) – Pseudagrion siamense, Brachythemis contaminata, Orthetrum luzonicum, Rhodothemis rufa and Rhyothemis obsolescens. With the combined data, a total of 34 species of Odonata (9 damselflies and 25 dragonflies) are currently known to Taman Timba Alam, Putrajaya.

Dragonflies and Damselflies of Tropicana Heights Kajang

Dragonflies and Damselflies of Tropicana Heights Kajang, Selangor

Central Park of Tropicana Heights Kajang has a few interconnected ponds (see the photos below). The park is well managed by the developer. I have to say it is a great urban landscape habitat for dragonfly watching. I visited the park on 10 August 2026 for dragonfly watching (from 10.30 am to 12.00 pm). I recorded 24 Odonata (dragonfly and damselfly) species - 20 species were dragonflies and 4 species were damselflies (see the species list at the end of this post). Species found in abundant in the park were Crocothemis servilia, Rhodothemis rufa, Rhyothemis variegata phyllis, Brachythemis contaminata, Urothemis signata and Ischnura senegalensis. Actually, I have been surveying the Odonata of the Central Park for more than 18 months. The other species found at the park (previous surveys) but not observed on 10 August 2026 are Pseudagrion australasiea, Diplacodes trivialis, Zyxomma petiolatum, Tramea transmarina, Orthetrum testaceum and Potamarcha congener. Therefore, a total of 30 Odonata species have so far been recorded from the Central Park of Tropicana Heights Kajang.

Dragonflies and Damselflies of Tasik Semenyih, Semenyih, Selangor

Dragonflies and Damselflies of Tasik Semenyih, Semenyih, Selangor

Tasik Semenyih is located along Jalan Broga. It is easily accessed through Taman Tasik Semenyih or Jalan Diamond City. The lake is not far from Semenyih town. The lake looks great, but many parts of the lake is covered by water hyacinth. I visited Tasik Semenyih on 7 August 2026 (from 10.15 am to 1.15 pm) to check the dragonflies and damselflies present there. I managed to record 17 species in 4 families - 4 were damselflies and 13 were dragonflies.

Dragonflying at Canal Park, Setia Alamsari

Dragonflying at Canal Park, Setia Alamsari, Selangor

Setia Alamsari is located in the larger Kajang area (many thought it is in Bangi arae), Selangor. It is about 5 km away from Universiti Kebangsaan Malaysia main campus. Canal Park is located within the township of Setia Alamsari, and it is a focus of recreation for the people living in the township. The park contains three nice ponds (actually retention ponds) with cemented walkways surrounding the ponds. I visited to Canal Park for dragonfly watching on 18 July 2026 (from 10 am to 1.30 pm). I managed to spot 21 Odonata species - 5 damselflies and 16 dragonflies.

Dragonflying at Putrajaya Wetland Park

Dragonflying at Putrajaya Wetland Park

I visited to Putrajaya Wetland Park on 4 July 2026 for dragonflying. I spotted 24 species of odonates. Diplacodes nebulosa was everywhere at the park. Trithemis pallidinervis was also present in a good number. Access to Putrajaya Wetland Park is free, and plenty of parking spaces are provided (free as well).

Please take note that Perbandanan Putrajaya just came up a few days ago with new guideline on photography activity at Parks in Putrajaya (including Putrajaya Wetland Park):

Dragonflying at the Pond Next to Kajang 2 KTM Station

A small pond is located next to the parking area of Kajang 2 KTM Station, Kajang, Selangor. The water edge length of the pond is about 200 m. I did dragonfly watching at the pond on 6-10 June 2026. To my surprise, 28 Odonata species (8 damselfly species and 20 dragonfly species) were recorded at the small pond. Interesting species spotted were Anax guttatus, Camacinia gigantea, Indothemis carnatica, Diplacodes nebulosa, Ceriagrion auranticum and Aciagrion borneense.

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.
