Rare
Under 5% of wildlife watchers report a Japanese Blue Mud-Dauber Wasp sighting in Tokyo on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 770th 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 Japanese Blue Mud-Dauber Wasp in Tokyo on a given day, so our monthly data shows no clear season.
4th of 4
Of the 4 cities where we can rate Japanese Blue Mud-Dauber Wasp sightings, Tokyo ranks 4th at under 5%. The best odds are in Tuen Mun (China, about 10%), Hong Kong (China, about 10%) and Taipei (Taiwan, under 5%).
GBIF citizen-science records
It is estimated from how often the Japanese Blue Mud-Dauber Wasp is recorded against all the insects logged in Tokyo (8 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.
