With luck
About 10% of wildlife watchers report a Marumba echephron sighting in Osaka on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 197th most-seen of the 352 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June to September
In those months about 10% of wildlife watchers report a Marumba echephron in Osaka on a given day, against under 5% in October to May, the lowest months. Those are among Osaka's wettest months, with about 180 mm of rain a month against 55 mm in January.

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.

Same family: Sphingidae
The closest relatives of the Marumba echephron that you can see in Osaka (family Sphingidae, Sphinx Moths) are White-Banded Hunter Hawkmoth (about 20%), Pellucid Hawkmoth (about 10%) and Maile Pilau Hornworm (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Marumba echephron is recorded against all the insects logged in Osaka (10 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.
