In 3 days ~10% in a week ~20%
Paracercion melanotum, also known as the eastern lilysquatter, is a species of damselfly in the family Coenagrionidae. It is known to occur in China, Taiwan, South Korea, Japan, Vietnam, India, Sri Lanka, Nepal, Java, Philippines and Thailand.
Species delimitation study based on COI, ITS, and morphological evidence concluded that P. pendulum and P. malayanum were synonymized as junior synonyms of P. melanotum. It is a medium sized damselfly with deep blue eyes. Its thorax is black on dorsum with very broad azure blue antehumeral stripes, which are very narrow or missing in Paracercion calamorum. Lateral sides of thorax are blue with a fine black line on the upper part of each lateral suture. No pruinescence compared to P. calamorum. Its wings are transparent and pterostigma is yellow, framed with heavy black nervures. Its abdomen is azure blue with broad black dorsal marks up to segment 7. Segment 2 has a distinct broad dorsal spot shaped like a thistle-head connected narrowly to a fine apical ring. This mark will help to distinguish it from Pseudagrion species. Segment 10 has a narrow mid-dorsal black streak. Female is dull green in colors... Wikipedia →

Rare
Under 5% of wildlife watchers report an Eastern Lilysquatter sighting in Beijing on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 260th most-seen of the 401 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report an Eastern Lilysquatter in Beijing on a given day, against under 5% in September to June, the lowest months. Those are among Beijing's wettest months, with about 130 mm of rain a month against almost none in January.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Eastern Lilysquatter sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 7
Of the 7 cities where we can rate Eastern Lilysquatter sightings, Beijing ranks 5th at under 5%. The best odds are in Nanjing (China, about 10%), Shanghai (China, about 10%) and Colombo [Sri Jayawardenepura Kotte] (Sri Lanka, about 10%).
GBIF citizen-science records
It is estimated from how often the Eastern Lilysquatter is recorded against all the insects logged in Beijing (9 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.
