Lestes elatus
In 3 days ~40% in a week ~60%
Lestes elatus is a species of damselfly in the family Lestidae, the spreadwings. It is known commonly as the emerald spreadwing. It is native to India, Thailand and Sri Lanka. It is a medium sized damselfly with greenish blue eyes. Thorax is brown on dorsum, changing to yellowish-brown on the sides. The dorsum of thorax is marked with a pair of narrow ante-humeral metallic green stripes expanded outwardly at the abdominal end like a hockey stick. There are three tiny black spots on the lateral sides. The brown color of the thorax will change to bluish-white due to pruinescence in adults. Its abdomen is pale yellowish brown at the sides in the young,
marked broadly on dorsum with metallic green, up to segment 8. The basal half of segment 9 is black and the apical half is yellowish brown. Segment 10 is yellowish brown. The yellowish-brown color of the abdomen will change to bluish-white due to pruinescence in the adults. Anal appendages are creamy yellow, broadly tipped with black in the young; entirely black in the adults. It can be easily distinguished from other species of this genus by its unique metallic thoracic stripes.

With luck
About 10% of wildlife watchers report an Asian Emerald Spreadwing sighting in Thrissur on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 79th most-seen of the 93 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report an Asian Emerald Spreadwing in Thrissur on a given day, against under 5% in September to May, the lowest months. That is one of Thrissur's wettest months, with about 400 mm of rain against 10 mm in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Asian Emerald Spreadwing sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 cities where we can rate Asian Emerald Spreadwing sightings, Thrissur has the highest daily chance: about 10%. Next come Chennai (India, about 10%) and Kochi (India, about 10%).
Same order: Odonata
The closest relatives of the Asian Emerald Spreadwing that you can see in Thrissur (order Odonata, Dragonflies and Damselflies) are Chalky Percher (about 50%), Pied Paddy Skimmer (about 40%) and Common Picture Wing (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Asian Emerald Spreadwing is recorded against all the insects logged in Thrissur (7 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
