A dragonfly is made up of three main body parts:
of dragonflies and damselflies
Adult Odonata (dragonflies and damselflies) possess two pairs of long, narrow, and net-veined wings. The wing veins of Odonata are fused at their bases and the wings cannot be folded over the body at rest.
|Sub equal front and hind wings are not similar||Both wings are equal and similar in size and shape|
|Dragonflies hold the wings horizontally outward when at rest||Damselflies hold the wings folded parallel with the abdomen or tilted upward|

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.
|Eyes separated widely from other||Eyes meet partially along a seam||Eyes barely touch at a centre point||Eyes meet along a long seam||Eyes close but not quite touching|

Insects of Borneo
Insects are diverse and dominant inhabitants of the tropical rainforests in Borneo Island. New species are discovered too often. Entomologists are still struggling to cope with the documentation of tropical insect diversity.
Red Dragonfly of Sabah
Most of the common dragonflies in Sabah are red coloured, especially from the family Libellulidae. Some red pecies are even confused as same species, for example the three species of Genus Neurothemis.
Ovipositor (Vulvar Lamina)
of Female Dragonflies and Damselflies
Female dragonflies have either one of the two method of depositing eggs from
1- using Ovipositor Structure
2- using Vulvar Lamina
Male do not have an ovipositor. Instead male dragonfly and damselfly have appendages.
Borneo has 150 species of wild fig trees. Most of them are found in forests of Sabah.
Prawn farming is a main commercial activities in Tawau. Spawners from Tawau are graded the best in Malaysia. For decades, Tawau has been exporting high-grade tiger prawns to several countries such as Korea, Japan, Taiwan, China, Vietnam, Singapore, Egypt and Australia.
