adult male

I still remember what I see in Erawan waterfall 3 years ago. It was my first field trip which make me surprised and hungry for next trip. Among other odonates, Coeliccia poungyi kicked my eyes with its blue synthorax markings and orange tail. In next tripes, I fortunately found immature and adult males in there. Immature male is very similar to adult C. chromothorax in yellow coloration but there are some differences as described below.

young male

Immature male is yellow body and dorsal broad stripes of synthorax is also yellow (similar to C. chromothorax). S8-10 is pale orange (while S9-10 of C. chromothorax is pale yellow). Color of the body of mature male changes from yellow to bright blue. S8-10 is orange. Female is similar to the male. S9-10 and cuadal appendages are orange yellow. Prothoracic markings are unique.

You can see this species in uplands and mountains in all parts of Thailand except Central and Southern ones all the year.
