A
very rare endemic dragonfly of small size inhabits ponds and stagnant pools
along streams of mid-hill rainforests. Museum specimens were so far collected from
Hanguranketha, Hatton and Kandy
(The dragonflies of Sri
Lanka – Terrence the
Fonseka). Therefore de Fonseka has noted that it is confined to the submontane
areas of the island. However above picture was taken at the Horagolla national park
(7° 8'29.44"N, 80° 5'2.83"E) a
lowland rain forest patch of about 33acres in Gampaha district 170 ft a.s.l.

Elusive Adjutant (Aethriamanta brevipennis)
Uncommon dragonfly. De Fonseka (The Dragonflies of Sri Lanka – 2000 ) mentioned that “it is unrepresented in the Museum collection and has not been recorded from here since first mentioned by Selys in 1897”. Fraser says that it is very local and rare. It is also said that it breeds in small weedy tanks surrounded by forest. However I have observed it in fair numbers during most of the months of the year at Anavilundhawa sanctuary -a wet land Ramsar site in North-Western province - and also once at Girithale tank of Polonnaruwa district.

Spine – Legged Redbolt (Rhodothemis rufa)
Brilliant scarlet red abdomen and thorax with no black markings of the male is the key to identify this insect from similar other dragonflies (Such as Scarlet basker). Sub adult males and females have a light yellowish mid dorsal stripe on segment 1 to 4. It is an uncommon dragonfly of lowland plains and breeds in weedy tanks, ponds, streams and channels while females hiding in surrounding jungle.

Green Skimmer (Orthetrum sabina)
Very common insect of plains and submontane regions of the country. Usually encountered in weedy edges of tanks, irrigation channels, paddy fields and perennial and seasonal ponds where it breeds. Both male and female are similar in shape and color. The extraordinary swollen abdomen of this dragonfly is remarkable and a useful identification feature of it.

Asian Pintail(Acisoma panorpoides)
Asian Pintail is a very small dragonfly of lowland plains up to lower hills. It has a very weak and short flight and hence keeps close to vegetation around heavily weeded water bodies such as tanks, marshes etc. and breed on them without moving far away. It is about 15-18mm of body size (Abdomen) and wing span of 16-22mm. Juvenile female is pale ochreous and which is replaced by azure blue of both sexes of adults.
