Scientific Name: Cratilla metallica
Common Name: Dark-tipped Forest-skimmer
These are moderately large dragonflies which are commonly found in closed forests in the nature reserve. Males have dark wing-tips and blue colour markings on the 3rd and 4th segments of the abdomen.
Females are larger with a shining, metallic blue thorax and abdomen, but without the blue colour markings.
Males like to perch for prolong period on twigs above forest pools. Females are not as commonly seen as males. A mating pair as seen in the above picture is rare.
