Monoceromyia pleuralis is a hoverfly that occurs in Japan. It is mostly black with yellow markings and brown markings on its wings. It was originally described by Coquillett in 1898 as Sphiximorpha pleuralis, but that genus was later lumped into Monoceromyia by Shannon. Wikipedia →

Rare
Under 5% of wildlife watchers report a Monoceromyia pleuralis sighting in Tokyo on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 585th most-seen of the 1013 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Monoceromyia pleuralis in Tokyo on a given day, so our monthly data shows no clear season.
Only Tokyo, in our data
Tokyo is the only city on Wallace's Line with enough records to rate Monoceromyia pleuralis sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Syrphidae
The closest relatives of the Monoceromyia pleuralis that you can see in Tokyo (family Syrphidae, Hover Flies) are Marmalade Hover Fly (about 10%), Helophilus eristaloideus (about 10%) and Phytomia zonata (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Monoceromyia pleuralis is recorded against all the insects logged in Tokyo (14 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.
