The blue riverdamsel, Pseudagrion microcephalum is a common species of damselfly in the family Coenagrionidae. It is also known as the blue sprite and blue grass dart. For many years, Pseudagrion microcephalum was considered to be a widespread species occurring across southern and eastern Asia, Australasia and the Pacific.
In 2026, Malte Seehausen and Milen Marinov reviewed the Pseudagrion microcephalum species complex and restricted Pseudagrion microcephalum to populations from the Indian subcontinent and Sri Lanka. As part of this revision, Australian, Papuan and Pacific populations previously identified as Pseudagrion microcephalum were reassigned to several distinct species, including Pseudagrion crenatum in Australia and New Guinea. Other populations from Southeast Asia and the western Pacific were also reassigned to newly recognised regional species.
This species can be found in India and Sri Lanka. It is a medium-sized damselfly with pale blue eyes, dark on top. They grow to 38mm in length. Its thorax is azure blue with black, broad dorsal stripes and narrow humeral stripes. Abdominal segments 1 and 2 are blue with... Wikipedia →

Possible
About 20% of wildlife watchers report a Blue Riverdamsel sighting in Kuching on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 26th most-seen of the 30 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March
In that month about 40% of wildlife watchers report a Blue Riverdamsel in Kuching on a given day, against under 5% in April–June, August–September and November–February, the lowest months.

GBIF citizen-science records
It is estimated from how often the Blue Riverdamsel is recorded against all the insects logged in Kuching (5 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.
