Dragonfly (Odonata) study

Report on Odonata Study done on a recent survey at Ayer Hitam Peatswamp Forest in the state of Johor, Malaysia.


Action Description:

Walking along the flooded path, one would be enchanted to see dozens of dragonflies and damselflies species buzzing around everywhere. It is unbelievable that this tiny area of 4000 hectares is home to 44 Odonata species and counting. The species recorded from Ayer Hitam Forest Reserve covers eight families thus representing 18% of the total species found in Peninsular Malaysia.

Species found abundantly in AHFR are Neurothemis fluctuans, Nannophya pygmaea, Ceriagrion cerinorubellum, Pseudagrion williamsoni, Pseudagrion microcephalum, Brachydiplax chalybea, Rhyothemis obsolescens, Rhodothemis rufa, Ictinogomphus decoratus, Orthetrum sabina and Brachygonia oculata.

The true alluvial swamp and peat swamp species recorded at AHFR are Amphicnemis gracilis, Archibasis viola, Brachygonia oculata, Elattoneura aurantiaca, Podolestes buwaldai, Podolestes orientalis, Ponorthemis serrata, Rhyothemis aterrima and Risiophlebia dohrni.

However, the most interesting species collected from AHFR is Indothemis carnatica. A few individuals of Indothemis carnatica were collected at a shallow water pool. Indothemis carnatica is so far known from India, Sri Lanka and Thailand, and it appears to be very scarce and local (Dow 2009). Another interesting species recorded from AHFR is Podolestes buwaldai. Podolestes buwaldai is a rare and local species confined to southern Peninsular Malaysia (Orr 2005). Only one specimen was collected/observed during the short sampling trip to AHFR.
