Rare
Under 5% of wildlife watchers report a Leucania yu sighting in Hong Kong on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 778th 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.
February
In that month about 10% of wildlife watchers report a Leucania yu in Hong Kong on a given day, against under 5% in March to January, the lowest months. That is one of Hong Kong's driest months, with about 30 mm of rain against 280 mm in June.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Leucania yu sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 3 cities where we can rate Leucania yu sightings, Hong Kong ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Kochi (India, under 5%).
Same family: Noctuidae
The closest relatives of the Leucania yu that you can see in Hong Kong (family Noctuidae, Cutworm Moths and Allies) are Flammona trilineata (about 10%), Oriental Leafworm Moth (about 10%) and Cerynea discontenta (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Leucania yu is recorded against all the insects logged in Hong Kong (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.
