Tholymis tillarga

Anisoptera
Species name: Tholymis tillarga
Family: Libellulidae
A male resting in the shade during the day photographed 
on Pulau Sapi an island off Kota Kinabalu  

This is another common crepuscular libellulid like the two Zyxomma ssp. (obtusum & petiolatum) and are found in similar habitats, i.e. drains, weedy ponds and other open bodies of water. 
Two males in flight at dusk

It is active at dusk, flying to and fro along drains and across ponds, the males are quite conspicuous for the white wing patches. In flight they are rather frustrating to photograph!

A female

The body of this medium-sized insect is orange-brown and the hindwing has an amber tinted patch followed by a patch of bluish white in the males while this white patch is absent in the female. Hence its common name - Coral-tailed Cloudwing.

Distribution: widespread in tropical Asia, Africa and Australasia.

Ceriagrion cerinorubellum

Zygoptera

Species Name: Ceriagrion cerinorubellum

Family: Coenagrionidae

Compared to the species in my previous post Ceriagrion cerinorubellum is widespread in tropical Asia but is no less beautiful, with its bluish green head and orange base and tip of the abdomen it is quite distinctive and cannot be mistaken for other species. The female is similarly coloured but darker. In India it is commonly known as the Orange-tailed Marsh Dart.


I have frequently found it in drains, ponds, and open swamps and sometimes in gardens near town.

Xiphiagrion cynomelas

Zygoptera
Species Name: Xiphiagrion cynomelas
Family: Coenagrionidae


This is another species of blue-coloured damselflies that are common in drains, lily ponds and stagnant bodies of water. They resemble Pseudagrion microcephalum but are smaller and both these species often share the same ponds. As with the latter species the male remained paired with the female while she lays her eggs onto water weeds and many pairs can be seen ovipositing en masse.

The male is blue on the sides of its thorax and black dorsally with two blue spots just behind the head, the abdomen is black tipped with blue. Females are similarly marked but dark olive instead of black as in the male. this dark area also lack blue spots.

Distribution: Borneo, Philippines, Indonesia.

Brachydiplax chalybea

Anisoptera
Species Name:
Brachydiplax chalybea

Family: Libellulidae
Brachydiplax chalybea is a moderate sized dragonfly commonly found in unshaded body of water, such as ponds, stagnant or slow flowing streams and drains. The males are a powder-blue in colour with hindwings that are tinted brown at the base and are often seen perched by the water and every now and then flying out to challenge any intruder that wanders into their small territory.

The females which are brownish in colour are less often seen and only appears at the water to mate and oviposite in the afternoon. This is a widespread species in tropical Asia.
