With luck
About 10% of wildlife watchers report a Japanese Blue Mud-Dauber Wasp sighting in Hong Kong on a given day, based on 31 verified sightings from GBIF citizen-science data. It is the 309th most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
April to July

GBIF citizen-science records
It is estimated from how often the Japanese Blue Mud-Dauber Wasp is recorded against all the insects logged in Hong Kong (31 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.
