Damselfly (24) - Prodasineura Collaris

Family : Protoneuridae

Common Name : Collared Threadtails

Status : Uncommon
Location : Upper Peirce

There are 4 Proidasineura species in Singapore namely Collaris, Humeralis, Interrupta & Notostigma). The blue marking on the head and thorax of Collaris and Notostigma look similar to me and I have difficulty identifying them. My guess is that this is a Collaris based on the white or blue marking on the tip of its tail. Again, I would appreciate it if someone could confirm it.

Damselfly - ID unknown

This damselfly was spotted around the same area where I found the Hyalina. They look quite similar but the colour of the thorax is slightly different. My guess is that it could be a juvenile Hyalina. I would appreciate it if someone could help to confirm the id of this species.

Dragonfly (17) - Risiophlebia Dohrni

Family : Libellulidae
Common Name : Triangled Small Percher
Status : Critically Endangered

Of Singapore's 124 recorded species of odonata, Risiophlebia Dohrni is one of the rarest. It is classified in the Singapore Red Data Book 2008 as a critically endangered species. This species can only be found in Upper Peirce. It is a relatively small size dragonfly with a unique unstraightened obdomen. Quite a cooperative species allowing me to take various shots.

Damselfly (23) - Libellago Aurantiaca

Family : Chlorocyphidae
Common name : Fiery Gem
Status : Rare
Location : Upper Peirce, Endau Rompin National Park
 

Libellago is the most unique genus in Singapore with its wings longer than the body. They are rare, beautiful and require pristine habitat. Their behaviour is fascinating too. There are only three Libellago species in Singapore checklist, one of which (Libellago Stigamtizans) is already extinct here.

Although Libellago Aurantiaca is less rarer that Hyalina (see my previous post), it is my most wanted species to photograph. I pariticularly like its vibrant colour of red and yellow and I have been searching for more than a year. So you can imagine how happy I was when I finally saw one at Upper Pierce, the same place where I shot the Hyalina. They love to perch lowerly, just above the water making it difficult to get a good angle. I only managed a good record shot.  I have visited this place many times subsequently but this beautiful damselfly could not be found anymore.

Afternote : I finally got an improvement shot of this species but in Singapore.  This was taken at a swift flowing stream at Endau Rompin National Park.

Damselfly (22) - Libellago Hyalina

Family : Chlorocyphidae
Common name : Clearwing Gem
Status : Critically Endangered
Location : Upper Peirce

Libellago Hyalina is a very rare damselfly. Upper Pierce is the only place where this species has been sited. It is therefore classified as critically endangered species. According to Mr Tang Hung Bun, an expert in Singapore Odonata, the common name of this species should be Clearwing Gem instead of Hyaline Jewel which was wrongly used by some people.

Libellago Hyalina is a confusing species because it has several colour forms for both male and female. It is not clear how many colour forms they actually have. The images below are some colour forms captured so far. There could be other colour forms that we are not aware of.

(Male, glowing purple form - 5 Dec 2009)

(Female, grey form - 5 Dec 2009)

(Younger Female, orange form - 3 Dec 2009)
