Paracercion Malayanum
''Paracercion melanotum'', also known as the eastern lilysquatter, is a species of damselfly in the family Coenagrionidae. It is known to occur in China, Taiwan, South Korea, Japan, Vietnam, India, Sri Lanka, Nepal, Java, Philippines and Thailand. Taxonomy Species delimitation study based on COI, ITS, and morphological evidence concluded that ''P. pendulum'' and ''P. malayanum'' were synonymized as junior synonyms of ''P. melanotum''. Description and habitat It is a medium sized damselfly with deep blue eyes. Its thorax is black on dorsum with very broad azure blue antehumeral stripes, which are very narrow or missing in ''Paracercion calamorum''. Lateral sides of thorax are blue with a fine black line on the upper part of each lateral suture. No pruinescence compared to ''P. calamorum''.

Damselflies
Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies. Most species fold the wings along the body when at rest, unlike dragonflies which hold the wings flat and away from the body. An ancient group, damselflies have existed since at least the Lower Permian, and are found on every continent except Antarctica. All damselflies are predatory insects; both nymphs and adults actively hunt and eat other insects. The nymphs are aquatic, with different species living in a variety of freshwater habitats including acidic bogs, ponds, lakes and rivers. The nymphs moult repeatedly, at the last moult climbing out of the water to undergo metamorphosis. The skin splits down the back, they emerge and inflate their wings and abdomen to gain their adult form. Their presence on a body of water indicates that it is relatively unpolluted, but the ...
