Rare
Under 5% of wildlife watchers report a Guava Moth sighting in Hong Kong on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 648th 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.
September and October
In those months about 10% of wildlife watchers report a Guava Moth in Hong Kong on a given day, against under 5% in November to August, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Guava Moth 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 2 cities where we can rate Guava Moth sightings, Hong Kong ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Brisbane (Australia, under 5%).
Same family: Erebidae
The closest relatives of the Guava Moth that you can see in Hong Kong (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Banyan Tussock Moth (about 20%), Orvasca subnotata (about 20%) and Zhejiang Tussock Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Guava Moth is recorded against all the insects logged in Hong Kong (12 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.
