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.

Rare
Under 5% of wildlife watchers report a Marumba gaschkewitschii sighting in Shanghai on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 185th most-seen of the 215 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and September–November
In those months about 10% of wildlife watchers report a Marumba gaschkewitschii in Shanghai on a given day, against under 5% in June–August and December–April, the lowest months.
2nd of 2
Of the 2 cities where we can rate Marumba gaschkewitschii sightings, Shanghai ranks 2nd at under 5%. The best odds are in Seoul (South Korea, about 10%).
Same family: Sphingidae
The closest relatives of the Marumba gaschkewitschii that you can see in Shanghai (family Sphingidae, Sphinx Moths) are Pellucid Hawkmoth (about 10%), White-Banded Hunter Hawkmoth (about 10%) and Plain Grey Hawkmoth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Marumba gaschkewitschii is recorded against all the insects logged in Shanghai (5 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.
