Rare
Under 5% of wildlife watchers report an Arippara indicator sighting in Hong Kong on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 680th 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.
April and August
In those months about 10% of wildlife watchers report an Arippara indicator in Hong Kong on a given day, against under 5% in May–July and September–March, the lowest months.
2nd of 2
Of the 2 cities where we can rate Arippara indicator sightings, Hong Kong ranks 2nd at under 5%. The best odds are in Chennai (India, about 10%).
Same family: Pyralidae
The closest relatives of the Arippara indicator that you can see in Hong Kong (family Pyralidae, Pyralid Snout Moths) are Guastica semilutea (about 10%), 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 Arippara indicator is recorded against all the insects logged in Hong Kong (11 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.
