Family: Corduliidae (Emeralds)
Scientific Name: Macromia cydippe
Common Name: Lesser Stream Cruiser
Macromia Cydippe is a very rare dragonfly species in Singapore. It was first recorded at Nee Soon Swamp Forest on 3rd January 2010. It is a forest species which prefers sluggish and clean-bottomed streams.
M.cydippe and M.cincta are both very similar in appearance. M. cydippe is characterised by it’s smaller size, more slenderer body, and a distinct yellow band at the base of the 7th abdominal segment. The inferior appendage of the male M. cydippe is much longer than it’s superior appendage.
I have seen this species, usually males, a couple of times at NSSF and MacRitchie Reservoir. Similarly to M. Cincta, this species like to perch motionlessly on twig just slightly above eye level.
