Dragonflies and damselflies (Odonata) are a group of aesthetic aquatic insects. Over 420 species of Odonata have been recorded for Malaysia (Peninsular Malaysia, Sabah and Sarawak). They are waiting for me to explore.

Neurobasis chinensis VS Neurobasis longipes
Differences between Neurobasis chinensis and Neurobasis longipes
Both Neurobasis chinensis and Neurobasis longipes occur in Peninsular Malaysia, with N. chinensis being much more common. To be honest, I only encountered N. longipes at a very few locations in Peninsular Malaysia. The male individuals of N. chinensis and N. longipes are quite similar. The base of hindwing has more extensive area of clear cells in N. longipes if compared to N. chinensis. It is actually quite difficult to tell apart the male individuals of both the species based on in-situ photos. However, the in-situ photos of female individuals may help to know the presence of which species at the site. The wing of female N. chinensis has two white spots while the female N. longipes has one white spot (see the photos below). When Neurobasis male individuals are spotted at one site, the female individuals are also frequently present at the site. I normally use this character to identify N. chinensis and N. longipes on site without catching them.

Urban Biodiversity of Odonata at Retention Ponds
Urban Biodiversity of Odonata at Retention Ponds
Department of Irrigation and Drainage (JPS) of Malaysia requires property development project exceeding 10.12 ha to construct retention or detention ponds under the Urban Stormwater Management Manual for Malaysia. These retention ponds normally have dual use - to turn into public recreational parks. I have visited a few of these retention ponds (recreational parks) for the past 2-3 years in Selangor – Shah Alam, Kajang and Semenyih. I must say that these retention ponds are good locations for dragonfly watching. To be honest, I was thrilled to observe some interesting Odonata species at these ponds in Selangor, such as Trithemis pallidinervis, Diplacodes nebulosa, Neurothemis tullia, Indothemis limbata, Chalybeothemis chini and Aethriamanta brevipennis, Tramea transmarina, Hydrobasileus croceus and Lestes decipiens. Indeed, these retention ponds are interesting urban landscape to promote urban biodiversity of Odonata.

Female Comparison of Indothemis limbata, Indothemis carnatica and Trithemis aurora
Female Comparison of Indothemis limbata, Indothemis carnatica and Trithemis aurora
Both Indothemis limbata and Indothemis carnatica are present in Peninsular Malaysia but absent in Borneo. Both species have the same aquatic habitat - ponds. The females of Indothemis limbata and Indothemis carnatica look alike, but yet they are distinguishable based on the extensiveness of tinted area at wing bases and the presence/absence of tinted wing tips (see photo images below). The female of Trithemis aurora may make one confused with the female of Indothemis limbata. Though both the females (Indothemis limbata and Trithemis aurora) have extensive tint on wing bases, they are readily be told apart by the presence/absence of tinted wing tips. Their dorsal thoracic and abdominal markings are actually different (see photo images below). One may ask about the female of Trithemis festiva. Well, the female of Trithemis festiva is also yellowish brown in colour with black marking. However, its thoracic and abdominal black marking pattern is different from those of Trithemis aurora and Indothemis limbata/carnatica. Click here to see the female of Trithemis festiva.

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
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.

Tasik Paya Pahlawan is located at Kampung Tradisi Paya Pahlawan, about 9 km away from Jitra, Kedah. I must say that the lake is beautiful. I had the opportunity to survey the dragonflies and damselflies of the lake on 26 July 2026 and 30 July 2026. I managed to record 17 Odonata species - 4 damselflies and 13 dragonflies.
