Pseudagrion rubriceps Selys, 1876

Family: Coenagrionidae
Scientific Name: Pseudagrion rubriceps
Common Name: Orange-faced Sprite

According to the book of dragonflies by Mr. Tang, this very rare damselfly has been found only at two locations in Singapore. These sightings were at Toa Payoh Town Park, and at the Central Catchment Nature Reserve.

My sighting of this species were at a very remote location at the western part of Singapore. The place has a small running stream surrounded by short and weedy vegetation.

The male has a striking bright orange face with olive green on the dorsum. It has beautiful light blue on the sides of the synthorax and blue markings on segment 10.

Agriocnemis minima (Selys, 1877) – An encounter with a sub-adult female with a tragic end!

Family: Coenagrionidae
Scientific Name: Agriocnemis minima
Common Name: NA

As mentioned in my previous posts, I have encountered and taken photos of adult male and various forms of female form from the very young to full adult and the aged. On October 2015, I have come across a very attractive sub-adult female. From the physical appearance, this female is very much the same in size and colour as the full adult female, except that the colour on the thorax is more yellowish and the two stripes at the synthorax are yellow.

This female individual was found near the edge of the forest’s wetland. Sadly, this female was preyed by a robber-fly after I had taken most of my shots.

Agriocnemis minima (Selys, 1877) – The Rare Adult Female

Family: Coenagrionidae
Scientific Name: Agriocnemis minima
Common Name: NA

Agriocnemis minima is a tiny and unrecorded species of damselfly that is only recently being discovered in Singapore. I have taken shots of males and young and aged females at a freshwater swamp in the Western part of Singapore.

The adult female has eluded me until very recently when I bumped into this female. After doing some research on the internet, it became apparent to me that this individual should be the adult female form of this species. It is very rare and I have only seen one individual of this form.

The eyes are brown on top and green below. It has yellow pterostigmata, and has yellow stripes on the synthorax. The sides of the thorax and abdomen are green and the dorsal side of the abdomen is black.

This species prefer to be in the open, grassy areas at the edge of the flooded wetland. It is probably the tiniest species of damselfly in Singapore with the abdomen plus appendages measuring just 14.5mm.

Pericnemis stictica Hagen in Selys, 1863

Family: Coenagrionidae
Scientific Name: Pericnemis stictica
Common Name: Dryad

This is a large and distinctive damselfly that lives and breeds in the dense understorey  of the Central Catchment Nature Reserve and Bukit Timah Nature Reserve. In fact, it is the largest of it’s family in South-East Asia.

In Singapore, it is mentioned that it has been recorded only once or twice a year in the past six years. It is primarily found in very dense vegetation in the forests. It mainly breeds in water-filled tree holes, buttress pans, bamboo stumps.

I have personally witnessed this species in the primary and secondary forests in Singapore, such as Upper Pierce Reservoir, Bukit Timah Nature Reserve and Chestnut Avenue forest.

This species has very long abdomen. The sides of the thorax is yellowish green, and the dorsum is dark. The eyes are green and the legs are yellow. Male has dark brown pterostigma, whilst female has white pterostigma. Female in general is larger and more robust.

This species is rare and scarce in Singapore.

IMG_2540a.2011.7.17
This large female was found in the Upper Pierce Reservoir forests. I was stunned when I first seen it. She was huge, in the context of the size of an average damselfly. She was flying with a bit of difficulty due to her heavy abdomen. She landed on the tip of a leaf with her abdomen hanging down. A stunning species. It has to be seen to believe!

Onychargia atrocyana (Selys, 1865)

Family: Coenagrionidae
Scientific Name: Onychargia atrocyana
Common Name: Shorttail, Marsh Dancer

Onychargia atrocyana is a very widely distributed damselfly species. It is distributed throughout South-East Asia, India and China. In Singapore, this species is uncommon and found mainly in densely vegetated and leafy-bottomed pools, marshes in swampy forested areas. I have personally come across this species at Chestnut avenue biking trail and the densely forested area in Mandai.

As this species breeds in leafy pools and marshes, it is often seen mating in tandem in these habitats.

Both males and females are stoutly built with short abdomen and long legs. Older males are blackish with hues of purple on the thorax. Young males have thick light yellowish stripes on the sides of the thorax.

Females thorax are also dark with two yellowish stripes on the dorsum. The abdomen is dark on the dorsal side and yellowish on the ventral side.

Archibasis rebeccae (Kemp, 1989)

Family: Coenagrionidae
Scientific Name: Archibasis rebeccae
Common Name: Rebecca’s Sprite

Male A.Rebeccae

Archibasis rebeccae is a very rare damselfly species that has been recorded only once in Singapore in the Central Catchment Nature Reserve on 2009. This species appears to be endemic to Peninsular Malaysia and Singapore. It occurs in lowland primary forests and streams.

This individual was taken on a trip to MacRitchie Reservoir’s forest in 2013. It was found along a quiet trail along Sime forest.

Male of this species are lighter blue. The appearance is very similar to A. melanocyana, and A. incisura. Segments 8 and 9 of the abdomen are blue. There are tiny blue spots on the dorsum of segment 10 of the abdomen. The superior appendages are strongly clubbed.

There is an interesting article about this species by Robin Ngiam.

It is frustratingly difficult to identify this species of damselfly. I hope my Id is correct.

Agriocnemis minima (Selys, 1877)

Family: Coenagrionidae
Scientific Name: Agriocnemis minima
Common Name: NA

According to the IUCN Red List of Threatened Species, 2014, Agriocnemis minima is a fairly and widely distributed species which occurs in Thailand’s agricultural fields. It is also found in Cambodia, P. Malaysia and Indonesia.

Mr Tang in his book – “Dragonflies of Singapore” did not mention of this species ever existed in Singapore. In late 2013, and early 2014, after searching at a stretch of wet marsh land in the Western part of Singapore on many occasions, I have finally found a small colony of this species residing at the edges of the shallow wetland.

This species is found in swamp forest and shallow marshes in the open forest. It is very tiny and prefers to perch lowly among reeds near the water edge.

The thorax of the adult males are green with black stripes at the synthorax. Abdomen are black dorsally and the last two segments are orange. The superior appendages are very prominent. They are longer than the inferior appendages and curve downward. It is orange in colour.  The pterostigma is yellowish in colour.

This is a young male.

Agriocnemis nana (Laidlaw, 1914)

Family: Coenagrionidae
Scientific Name: Agriocnemis nana
Common Name: Dwarf Wisp

This tiny damselfly is the smallest damselfly in Singapore. It is found in grass marshes in open forests, small streams and vegetation around edges of the central catchment reservoirs. It is very rare and localised in Singapore. The only places where I have found this species is at the water edges of the MacRitchie reservoir.
 The male has a blue thorax with black strips and blue abdomen. The labrum is blue and the pterostigma is bluish-white.

Which Agriocnemis sp?

Family: Coenagrionidae
Scientific Name: Agriocnemis Sp.

This Agriocnemis sp. was taken at a small stream near Mandai forests. I have no idea what is the species, although I am inclined to think it is Agriocnemis pygmaea which is very rare in Singapore. This is the only picture I have of this individual.

Hope some experts can help to id.
