Scientific Name: Ceriagrion chaoi
Common Name: Fiery Coraltail
Ceriagrion chaoi is a rare damselfly species that has been found only at very few places in Singapore, such as Bishan Park, and MacRitchie Reservoir.
In June 2013, I saw this species at an unrecorded place at the Western side of the Central Catchment Nature Reserve. There are at least a pair of this damselfly ovipositing on the submerged water plants at the reservoir. It seems that this species only appear late in the morning and males are more likely to be seen, whilst females are less common.
The male has a striking red abdomen and an olive green thorax. The eyes and mouth are red. Females are less striking with dull olive green thorax.
