Rare
Under 5% of wildlife watchers report a Falcate Oak Blue sighting in Hong Kong on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1005th 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 20%, if each day is a fresh chance.
January
In that month about 10% of wildlife watchers report a Falcate Oak Blue in Hong Kong on a given day, against under 5% in February to December, the lowest months. That is one of Hong Kong's driest months, with about 35 mm of rain against 280 mm in June.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Falcate Oak Blue sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 5
Of the 5 cities where we can rate Falcate Oak Blue sightings, Hong Kong ranks 5th at under 5%. The best odds are in Fuzhou (China, about 10%), Tuen Mun (China, about 10%) and Kolkata (India, about 10%).
Same family: Lycaenidae
The closest relatives of the Falcate Oak Blue that you can see in Hong Kong (family Lycaenidae, Gossamer-winged Butterflies) are Pale Grass Blue (about 20%), Plains Cupid (about 20%) and Abisara echeria (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Falcate Oak Blue is recorded against all the insects logged in Hong Kong (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.
