110. Echo modesta (Laidlaw, 1902)

Number: 110
Family: Calopterygidae
Genus: Echo 
Species: Echo modesta
Common name(s): N/A
Thai name(s): แมลงปอเข็มน้ำตกใหญ่หน้าขาว, แมลงปอเข็มน้ำตกใหญ่อีโค
Habitat: Heavily forested upland streams
Province(s) sighted: Lamklong Ngu NP (Kanchanaburi).
Sightings (by me): Rare
In flight (that I have seen): March (longer, I'm sure)

Another member of the Calopterygidae family and the 6th I have now seen, is Echo modesta. It's a stunning damselfly and is easily recognizable with its white face. 
The male
It's similar to other species in the family, but has a kind of 'box-shaped' thorax. The wings are also hyaline. The easy way to spot this species, however, is the mature male's white face. 

The sub-adult male
I was fortunate to spot a young male, which is the same as the adult, but hasn't yet developed a white square on its face.

It likes particularly dark, shaded areas under tree canopy and the species can be seen in upland forested areas along the west of Thailand, all year round.  I saw 2 adult males and a young male. Unfortunately, I didn't see a female.
