Prodasineura collaris - In Wheel

I have been observing Prodasineura collaris for quite some time. It is quite hard to see them in wheel though I have seen them in tandem on many occassions. Today, I had the luck to spot a wheel pair of P. collaris......

In Wheel - Neurothemis fluctuans

Neurothemis fluctuans is one of the most common dragonfly species in Peninsular Malaysia. Wherever you go, you just won't miss N. fluctuans. However, taking a good picture showing a pair of N. fluctuans in wheel is just challenging. Today, I managed to get a more satisfied picture of N. fluctuans in wheel. I need to try harder for better picture..........

Ischnura senegalensis Again

Today I spotted a few green form females of mating Ischnura senegalensis. I managed to snap a few good shots on them. I also spotted one male-like female. It looks like the male-like female is less common compared to female of green and orange forms in UKM campus. Click here and here to see previous entries on I. senegalensis.

Copera vittata and C. marginipes are belonged to family Platycnemididae. As the male, the female of the both Copera species also look alike but close inspection is easily to tell them apart.

Mortonagrion aborense

Lately, I have been spotting Mortonagrion aborense during my field work. Whenever I spotted them hanging around slow flowing stremlets, their number was never big - just a few of them (maybe 2-3 individuals). Anyway, I managed to get a few good shots of male and female. I need more patience to look for them in wheel........... wish me luck :). I did have a photo showing a tandem pair of M. aborense with the female in the middle of ovipositing (click here to see the photo).

Ischnura senegalensis

Ischnura senegalensis is a small size but robust damselfly species normally found at open distribut grassy habitats. It likes marshes and grassy lake sides. The male is in blue and greenish colour, and the tail has blue marking. However, the female is quite variable. There are three colour forms for female - male-like colour, olive colour and orange colour. I have seen male-like and orange colour forms of female. I should pay extra attention to olive colour form female, and I just need a good photo of olive colour form female for my photo collection......
