Dragonflies and damselflies

I don't really know the difference between dragonflies and damselflies so tend to call them all dragonflies. They belong to the order Odonata.

They both have 2 pairs of large wings that are delicate yet detailed. Dragonflies usually spread their wings when resting. Damselflies have the wings folded over & parallel to the body when resting.

The following photos were taken from my balcony in KL.

This one was on a cable so I had to use the zoom -
