Camacinia gigantea  
Colour and pattern suggest a huge Neurothemis but habits very different. M hw 47-52 mm; similar to F but basal wing colouring pale and less extensive. Lowland ponds and lakes in open areas, especially along the landward margins of mangroves. Larvae probably semi-pelagic; of similar outline to Hydrobasileus croceus but more elongate and ab lacking dorsal spines and lateral spines on S8. Adults fly rapidly, sailing over long reaches of their habitat, perching infrequently. Widespread but rare in Indo-Australian tropics.  



Camacinia gigantea is the largest of the Libellulidae (hw, 45-47 mm) and unmistakable by virtue of its extensive opaque brownish-red areas on the basal part of the wings. It is a splendid insect, at first suggestive of a very large Neurothemis. The coloration is fainter in teneral individuals and females. It is a widespread lowland species, in Borneo rarely encountered on lakes and in lagoons on the landward side of mangroves.

The compound eyes of dragonflies

Dragonflies and damselflies have large compound eyes that can see in all directions. When the compound eye is magnified several hundred times, each individual facet (ommatidium) is shown to be hexagonal in shape.



Ovipositor (Vulvar Lamina)
of Female Dragonflies and Damselflies

Female dragonflies have either one of the two method of depositing eggs from the abdomen:
1- using Ovipositor Structure
2- using Vulvar Lamina

Male do not have an ovipositor. Instead male dragonfly and damselfly have appendages.
