With luck
About 10% of wildlife watchers report a Guastica semilutea sighting in Hong Kong on a given day, based on 146 verified sightings from GBIF citizen-science data. It is the 69th most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
July–August and October
In those months about 20% of wildlife watchers report a Guastica semilutea in Hong Kong on a given day, against about 10% in September and November–June, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Guastica semilutea sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Hong Kong, in our data
Hong Kong is the only city on Wallace's Line with enough records to rate Guastica semilutea sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Pyralidae
The closest relatives of the Guastica semilutea that you can see in Hong Kong (family Pyralidae, Pyralid Snout Moths) are Nephopterix ochribasalis (about 10%) and Copamyntis leptocosma (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Guastica semilutea is recorded against all the insects logged in Hong Kong (146 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.
