The 3 families of dragonflies found in Borneo Island:

1 Family of Aeshnidae

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.

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.

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.

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.
