Rare
Under 5% of wildlife watchers report a Sympetrum parvulum sighting in Tokyo on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 612th 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 Sympetrum parvulum 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 Sympetrum parvulum sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Sympetrum
The closest relatives of the Sympetrum parvulum that you can see in Tokyo (genus Sympetrum, Meadowhawks) are Autumn Darter (about 10%), Four-Tipped Darter (about 10%) and Banded Darter (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sympetrum parvulum is recorded against all the insects logged in Tokyo (16 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.
