219. Chalybeothemis fluviatilis Lieftinck, 1933

Number: 219 / Family: Libellulidae / Genus: Chalybeothemis
Species: Chalybeothemis fluviatillis / Green-eyed Percher 
Habitat: Peat Swamp Forest
Province(s) seen (by me): Narathiwat 
In flight: August / Sightings (by me): Rare
Species easily confused with: N/A

Another incredibly rare species for Thailand and only known from one area is Chalybeotemis fluviatillis, commonly known as the Green-eyed Percher. Difficult to approach, it was even harder to spot, though we did eventually spot 7-8 individuals flitting around the edge of one smallish peat swamp pond outside Sirindhorn Peat Swamp. Both Noppadon and I were really, really happy to see this species with its glorious eyes! Sadly, we only saw males. No females were present - likely hiding deep in the reeds.

The Male
Small in size, the male has striking green eyes and unique markings on the abdomen.





Check out those gorgeous green eyes...
