My Other Main Blog on Odonata

I spend more time on my other Odonata blog:

Dragonflies and Damselflies of Malaysia

https://dragonfly-and-damselfly-malaysia.blogspot.com/

Females of Heliocypha biforata, Heliocypha perforata and Aristocypha fenestrella

Aristocypha fenestrella, Heliocypha biforata and Heliocypha perforata are found in Peninsular Malaysia. The size of  these species is not much different from each other. The males of these species  are easily told apart by the coloration of their body. On the other hand, the females have quite similar coloration. However, they can be distinguished by the yellow marking of their bodies (see the below photos).

 

Cratilla lineata vs Cratilla metallica - Famale

The females of Cratilla lineata and Cratilla metallica are not too hard to be told apart. At first glance, the wing tips for both the females are tinted. However, the edge of the tinted area is more defined and darker in C. metallica than C. lineata. Apart from that, the colour of C. metallica is metallic but not so in C. lineata.

Indothemis carnatica VS Indothemis limbata

Two Indothemis species are found in Malaysia – Indothemis carnatica and Indothemis limbata. Both the species are dark blue in colour, and they are normally found at ponds. The matured males of the species are not too hard to be distinguished by two characters. In I. carnatica, the wing tips are not tinted and the tail end (anal appendages) is slight lighter (a bit cream in colour). On the other hand, I. limbata have tinted wing tips and the tail end is dark in colour.
