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.

A final lateral view. Yellowish thorax and striking green stripes at the side of the abdomen.

This small midget has largely been overlooked by observers as they are so tiny. It is hope that they will permanently make this patch of wetland their home.

Gynacantha basiguttata – female ovipositing.

Family: Aeshnidae
Scientific Name: Gynacantha basiguttata
Common Name: Spoon-tailed Duskhawker

Encountering a rare female Gynacantha basiguttata was lucky enough, let alone a female which oviposit at a forest pool in the secondary forest near Mandai. It was around 10 plus in the morning when I arrived. The forest pool was almost dried up after days of dry weather. It was flooded with fallen leaves and broken branches. Although it was without any trace of water, the soil was quite damp.

This female suddenly appears and starts to oviposit on the damp soil. she spent quite awhile surveying the area and looking for suitable spots. She will hang around at a particular spot for awhile, lay her eggs and then move on to another spot.

The dried up forest pool is quite big, about the size of a basket ball court. From far, the female has already started ovipositing her eggs.
A tiny speck of green amongst a sea of fallen leaves.

She randomly chose her breeding spots, which include decayed leaves, damp soil and rotten logs.

I think that is a heavily rotten tree trunk where she is ovipositing on.
Dorsal view. See how she stretch out her abdomen.
Another closer dorsal view shot – she is oblivious to my presence.
Frontal view with two large greenish eyes. Dorsum and both sides of the thorax is greenish too.
A solitary male was seen resting at the nearby branch.

This place is indeed a perfect breeding place for the forest-dwelling duskhawkers.

Macromia cydippe Laidlaw, 1922 – female

Family: Corduliidae (Emeralds)
Scientific Name: Macromia cydippe
Common Name: Lesser Stream Cruiser

The female of Macromia cydippe is extremely rare, and I believe, has never been recorded in Singapore. In October 2013, I chanced upon a female of this species perched on a branch about 2 metres away from the ground at MacRitchie Reservoir. Immediately I knew that this could be the rare M.cydippe from the distinct whitish band on it’s abdomen.

The eyes of this female appeared to be greyish, the band is more whitish than yellowish and the pair of front wings is tinted with brownish patch.

Side view. Notice the striking wide stripe at the thorax and the whitish band at segment 7 of the abdomen

Apparently, the female was waiting to mate with the male as I have also seen at least one male perching near to where the female was found.

From my observation, this species is quite widespread but very localised in Singapore. So far, it has been sited at a few locations such as NSSF, MacRitchie Reservoir and Venus Drive.

Libellago hyalina, Selys, 1859 – Female

Family: Chlorocyphidae (Jewels)
Scientific Name: Libellago hyalina
Common Name: Clearwing Gem

The female of Libellago hyalina is as attractive as the male, in my opinion. The abdomen of the female has two colour form, a striking golden-orange coloured form and the dark grey coloured form.

This species usually appear in late morning, perching lowly on grass or twigs. They seem to be very active in the late morning to noon.

The abdomen of the young female is golden-orange in colour.

This is another coloured form, dark grey.
