With luck
About 10% of wildlife watchers report a Slender Blue Skimmer sighting in Hong Kong on a given day, based on 33 verified sightings from GBIF citizen-science data. It is the 362nd most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April to September
In those months about 10% of wildlife watchers report a Slender Blue Skimmer in Hong Kong on a given day, against under 5% in October to March, the lowest months. Those are among Hong Kong's wettest months, with about 190 mm of rain a month against 25 mm in December.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Slender Blue Skimmer sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 13
Of the 13 cities where we can rate Slender Blue Skimmer sightings, Hong Kong ranks 10th at about 10%. The best odds are in Thiruvananthapuram (India, about 40%), Kozhikode (India, about 20%) and Mysuru (India, about 20%).
Same genus: Orthetrum
The closest relatives of the Slender Blue Skimmer that you can see in Hong Kong (genus Orthetrum) are Blue Marsh Hawk (about 30%), Crimson-Tailed Marsh Hawk (about 20%) and Brown-Backed Red Marsh Hawk (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Slender Blue Skimmer is recorded against all the insects logged in Hong Kong (33 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.
