Rare
Under 5% of wildlife watchers report a Crotalaria Moth 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Crotalaria Moth in Hong Kong on a given day, so our monthly data shows no clear season.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Crotalaria 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.
4th of 5
Of the 5 cities where we can rate Crotalaria Moth sightings, Hong Kong ranks 4th at under 5%. The best odds are in Brisbane (Australia, about 10%), New Delhi (India, under 5%) and Kochi (India, under 5%).
Same family: Erebidae
The closest relatives of the Crotalaria 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 Crotalaria Moth 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.
