Possible
About 30% of wildlife watchers report a Tropical Fritillary sighting in Suzhou on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 65 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
August
In that month about 40% of wildlife watchers report a Tropical Fritillary in Suzhou on a given day, against under 5% in February–March and December, the lowest months. That is one of Suzhou's wettest months, with about 160 mm of rain against 45 mm in December.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Tropical Fritillary sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 28
Of the 28 cities where we can rate Tropical Fritillary sightings, Suzhou ranks 8th at about 30%. The best odds are in Gwangju (South Korea, about 50%), Naha (Japan, about 40%) and Daejeon (South Korea, about 40%).
Same family: Nymphalidae
The closest relatives of the Tropical Fritillary that you can see in Suzhou (family Nymphalidae, Brush-footed Butterflies) are Asian Comma (about 30%), Lesser Purple Emperor (about 20%) and Blue Admiral (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tropical Fritillary is recorded against all the insects logged in Suzhou (25 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.
