A male Lestes praemorsus decipiens Kirby, 1893. Perching with wings
half open, a physically unique from normal damselflies.
Though geographically wide spread in tropical Asia but quantity very few
to find. Making it more difficult to see is its habit of perching
vertically while other damselflies are more easily seen standing
horizontally.

Lestes praemorsus decipiens have a hockey-stick-shape abdomen. They
like dandling with their long thin hockey abdomens as if practicing
golfing.
Common in lowland swamps and drains especially disturbed
habit age. Perches with wings half open. Wide spread in tropical Asia.

From the very first time I saw a Lestes praemorsus decipiens last
year, I love this damselfly for its soft and warm feeling. Very
different to other damselflies that are smooth and shinning to the eyes.
A close look gave the explanation why. Lestes praemorsus decipiens are
wearing a layer of thick short fur covering the whole body from head,
thorax to abdomen like those warm blooded animals. Other damselflies are
having a layer of plastic-like smooth skin with sharp long hairs.

The same male Lestes praemorsus decipiens of previous 3 pictures.
Last 3 sections (section 8, 9, 10) of the abdomen. The abdomen, as well
as head and thorax, is covered with a layer of thick short fur. This
outlook gives Lestes praemorsus decipiens a soft and warm feeling to the
eyes which is different with the smooth and shinning look of other
damselflies and dragonflies.
