FOODS OF ODONATA
Dragonflies and Damselflies feed on insects
A small dragonfly eat mosquitoes every day. While the larger dragonflies eat
small insects like moth, butterflies, flies and sometimes each other.
Dragonflies are not venomous and they kill and eat by ripping and tearing apart
their prey usually head first.
From their hunting habits we can separate dragonflies into :
1-Hawkers
2-Darters
Hawkers are often seen continuously flying in circles. They scan the area,
attack, eat in flight and re attack.
Darters can be seen resting on a twig or leaf and darts out every now and then
to attack a prey flying by and then return to the twig.
The 3 families of dragonflies found in Borneo Island:
1 Family of Aeshnidae

INTRODUCTION TO THE DAMSELFLIES OF SABAH, BORNEO ISLAND
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.
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.

the abdomen:
1- using Ovipositor Structure
2- using Vulvar Lamina
Male do not have an ovipositor. Instead male dragonfly and damselfly have appendages.
