Stripe-headed Threadtail

Prodasineura sita


The common name refers to stripe on top of vertex connecting the two eyes, which also show pale stripe. The thin dorsal stripe on the thorax and pair of lateral stripes. In males, 'stripe head is a metallic reflection and not visible unless a close view is had. Older males become very dark brown, almost black, but in contrast to Dark-glittering Threadtail never have a metallic purple sheen. Females' head stripes and thorax paler and more conspicuous than male's. Pale stripes across frons.


Perching near the small pond in my garden.


Endemic to Sri Lanka; status is least concern. Widely distributed from lowlands to lower mid-hills. Most common in the wet zone. Prefers densely vegetated waterways. Not uncommon in ditches and other waterways even in a city suburb.
