Rare
Under 5% of wildlife watchers report an Isyndus obscurus sighting in Tokyo on a given day, based on 35 verified sightings from GBIF citizen-science data. It is the 314th 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.
October
In that month about 10% of wildlife watchers report an Isyndus obscurus in Tokyo on a given day, against under 5% in November to September, the lowest months. That is one of Tokyo's wettest months, with about 250 mm of rain against 75 mm in February.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Isyndus obscurus sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 cities where we can rate Isyndus obscurus sightings, Tokyo ranks 3rd at under 5%. The best odds are in Nanjing (China, about 10%) and Seoul (South Korea, under 5%).
Same family: Reduviidae
The closest relatives of the Isyndus obscurus that you can see in Tokyo (family Reduviidae, Assassin Bugs) are Japanese Assassin Bug (about 10%) and Sphedanolestes impressicollis (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Isyndus obscurus is recorded against all the insects logged in Tokyo (35 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.
