Female - Trithemis aurora vs Trithemis festiva

I was asked some time ago by a visitor to my blog how to tell apart the females of Trithemis aurora from Trithemis festiva. The colouration of males for these two species is so distinct that you still could distinguish them easily without wearing glasses (if your vision is impaired)... hehe. You may click here to view the male T. aurora and here to view the male T. festiva. The marking on the abdomen-thorax of female T. aurora is different from that of the female T. festiva.

Orthetrum chrysis in wheel

I saw so many wheel pairs of Orthetrum chrysis in Bangi Forest Reserve today....

Onychothemis testacea

Onychothemis testacea is definitely rare in Peninsular Malaysia. I have so far spotted O. testacea at two locations in Peninsular Malaysia - one at Sg Bebar, Pahang and the other one at Bangi Forest Reserve, Selangor. I photographed a male before (click here to view) some time ago. Now, I finally have a a photo of female O. testacea. The female resembles the male in colouration.

Seremban Lake Garden

I arrived at Klana Resort Hotel, Seremban this late afternoon to attend a seminar. I saw a small lake (Seremban Lake Garden; shown in the photos below) not too far from the hotel. After checking in the hotel, I went to the lake to do Odonata observation for two hours (5-7 pm). The weather was good, and I went around the lake looking for Odonata. I spotted ten species of Odonata. Brachythemis contaminata and Pseudagrion microcephalum were present in abundant at the lake in late afternoon.

I visited again Seremban Lake Garden in the morning two day later. I stayed there for roughly two hours (10am - 12pm). I spotted another 11 species. These additional species have been added to the checklist. Now, the checklist contains 21 species altogether.
