Egg Laying of Tramea transmarina

Egg Laying of Tramea transmarina

Tramea transmarina is a pond species. The egg-laying is normally performed in the mid day. During the process of egg laying, the male clasps on the female forming a tandem pair. The flying tandem pair will look for suitable sites at the pond for egg laying. The male will unclasps the female briefly letting her to release eggs on the surface of water. Then, immediately the male will clasp the female forming again a tandem pair. The tandem pair will keep on flying to look for other suitable sites at the pond to lay eggs. Sometime, the female may lay eggs alone without the presence of the male.

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.

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.
