Scientific Name: Aciagrion hisopa
Common Name: Blue Slim
Aciagrion hisopa is a very rare and small damselfly which has rarely been encountered in Singapore. It’s habitats open shallow and weedy ponds and drains in disturbed areas. According to record, one female was found in Normanton Park in 1986. A pair was found at Chestnut Ave in 2009. There are no other records since then.
In May 2016, I was at the Central Nature Reserve and accidentally bumped into a Aciagrion hisopa, female in the bushes. The area was very remote and isolated, sparely forested and near to an open wetland.
It was fluttering around the bushes looking for it’s meal. The damselfly was so small that it’s almost impossible to track it as it moves around the bushes.
Aciaprion hisopa is very similar to Pseudagrion species, except that it has a lighter build and the wings are narrower. The spotted female has the sides of the thorax blue with distinctive black and orange stripes on the dorsum. The last three abdominal segments are blue. The eyes are green.
Here is the damselfly resting at the tip of the leaf inside the forest.
Although very rare, I believe this species can still be found in our vast forest reserves.
