Agriocnemis minima (Selys, 1877)

Family: Coenagrionidae
Scientific Name: Agriocnemis minima
Common Name: NA

According to the IUCN Red List of Threatened Species, 2014, Agriocnemis minima is a fairly and widely distributed species which occurs in Thailand’s agricultural fields. It is also found in Cambodia, P. Malaysia and Indonesia.

Mr Tang in his book – “Dragonflies of Singapore” did not mention of this species ever existed in Singapore. In late 2013, and early 2014, after searching at a stretch of wet marsh land in the Western part of Singapore on many occasions, I have finally found a small colony of this species residing at the edges of the shallow wetland.

This species is found in swamp forest and shallow marshes in the open forest. It is very tiny and prefers to perch lowly among reeds near the water edge.

The thorax of the adult males are green with black stripes at the synthorax. Abdomen are black dorsally and the last two segments are orange. The superior appendages are very prominent. They are longer than the inferior appendages and curve downward. It is orange in colour.  The pterostigma is yellowish in colour.

This is a young male.

This species is a new record in Singapore. Let’s hope that it will survive in this small wetland as this place is quite remote and practically no disturbance from any human activities.
