With luck
About 10% of wildlife watchers report an Apriona rugicollis sighting in Hangzhou on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 38th most-seen of the 172 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
June and July
In those months about 20% of wildlife watchers report an Apriona rugicollis in Hangzhou on a given day, against under 5% in September to May, the lowest months. Those are among Hangzhou's wettest months, with about 200 mm of rain a month against 65 mm in December.

GBIF citizen-science records
It is estimated from how often the Apriona rugicollis is recorded against all the insects logged in Hangzhou (17 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.
