With luck
About 10% of wildlife watchers report a Marumba echephron sighting in Tokyo on a given day, based on 80 verified sightings from GBIF citizen-science data. It is the 169th most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
May to September
In those months about 10% of wildlife watchers report a Marumba echephron in Tokyo on a given day, against under 5% in October to April, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Marumba echephron sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 3 cities where we can rate Marumba echephron sightings, Tokyo ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Nagoya (Japan, about 10%).
GBIF citizen-science records
It is estimated from how often the Marumba echephron is recorded against all the insects logged in Tokyo (80 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.
