Likely
About 40% of wildlife watchers report a Tropical Fritillary sighting in Daejeon on a given day, based on 41 verified sightings from GBIF citizen-science data. It is the most-seen of the 53 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
October
In that month about 80% of wildlife watchers report a Tropical Fritillary in Daejeon on a given day, against under 5% in May and December–January, the lowest months. That is one of Daejeon's driest months, with about 55 mm of rain against 320 mm in July.
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.
3rd of 28
Of the 28 cities where we can rate Tropical Fritillary sightings, Daejeon ranks 3rd at about 40%. The best odds are in Gwangju (South Korea, about 50%) and Naha (Japan, about 40%).
Same family: Nymphalidae
The closest relatives of the Tropical Fritillary that you can see in Daejeon (family Nymphalidae, Brush-footed Butterflies) are Asian Comma (about 30%), Red Ring Skirt (about 20%) and Common Beak (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 Daejeon (41 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.
