Marumba gaschkewitschii is a species of moth of the family Sphingidae first described by Otto Vasilievich Bremer and William (Wasilii) Grey in 1853. It is found in eastern Asia (see subspecies section). The wingspan is 70–92 mm.
Adults are on wing from mid-May to late August in Korea. There are one to three generations per year. Larvae have been recorded on Eriobotrya japonica and various Malus, Prunus and Pyrus species. It is considered a pest on Prunus mume. Most host plants are from the family Rosaceae, but there are also records for subspecies M. g. irata feeding on Salix. There are also confirmed records on Ziziphus mauritiana and Prunus armeniaca.

With luck
About 10% of wildlife watchers report a Marumba gaschkewitschii sighting in Seoul on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 170th most-seen of the 525 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.
June to August
In those months about 10% of wildlife watchers report a Marumba gaschkewitschii in Seoul on a given day, against under 5% in September to May, the lowest months. Those are among Seoul's wettest months, with about 250 mm of rain a month against 20 mm in January.

GBIF citizen-science records
It is estimated from how often the Marumba gaschkewitschii is recorded against all the insects logged in Seoul (19 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.
