Sympetrum pedemontanum
In 3 days ~20% in a week ~40%
Sympetrum pedemontanum, the banded darter, is a dragonfly belonging to the genus Sympetrum. It is characterized by its small stature, dark wing bands, and red or yellow body. It lives in areas with low vegetation and stagnant or weakly flowing bodies of water. Although debate exists regarding the taxa's relationship to others in its genus, it can most commonly be identified by its wing bands, bilobed prothorax, and possibly its genitalia.
It is wide spread across Eurasia and is known for its tendency to cohabitate in artificial habitats. It is Commonly found in irrigated hay meadows, semipermanent marsh lands, rice paddy fields, and grasslands. Showing a preference for banks with comparatively lower levels of vegetation, they have a tendency for residing around trimmed grass and bodies of water as this is where they lay their eggs. Banded darters lay their eggs in stagnant or weakly flowing shallow water. Members of the Sympetrum family have the ability to detect horizontally polarized reflected light which allows them to find bodies of water and subsequently make their homes there.

With luck
About 10% of wildlife watchers report a Banded Darter sighting in Tokyo on a given day, based on 160 verified sightings from GBIF citizen-science data. It is the 111th most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June to November
In those months about 10% of wildlife watchers report a Banded Darter in Tokyo on a given day, against under 5% in December to May, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Banded Darter sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 9
Of the 9 cities where we can rate Banded Darter sightings, Tokyo ranks 4th at about 10%. The best odds are in Daegu (South Korea, about 20%), Milan (Italy, about 10%) and Seoul (South Korea, about 10%).
Same genus: Sympetrum
The closest relatives of the Banded Darter that you can see in Tokyo (genus Sympetrum, Meadowhawks) are Autumn Darter (about 10%), Four-Tipped Darter (about 10%) and Sympetrum baccha (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Banded Darter is recorded against all the insects logged in Tokyo (160 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.
