Macromia cydippe Laidlaw, 1922 – female

Family: Corduliidae (Emeralds)
Scientific Name: Macromia cydippe
Common Name: Lesser Stream Cruiser

The female of Macromia cydippe is extremely rare, and I believe, has never been recorded in Singapore. In October 2013, I chanced upon a female of this species perched on a branch about 2 metres away from the ground at MacRitchie Reservoir. Immediately I knew that this could be the rare M.cydippe from the distinct whitish band on it’s abdomen.

The eyes of this female appeared to be greyish, the band is more whitish than yellowish and the pair of front wings is tinted with brownish patch.

Apparently, the female was waiting to mate with the male as I have also seen at least one male perching near to where the female was found.

From my observation, this species is quite widespread but very localised in Singapore. So far, it has been sited at a few locations such as NSSF, MacRitchie Reservoir and Venus Drive.
