Acrida cinerea
In 3 days ~10% in a week ~20%
Acrida cinerea, sometimes called the Oriental longheaded grasshopper/locust or the Chinese grasshopper though this name is also applied to Oxya chinensis, is a member of the Acrididae family. Like other members of the genus Acrida, Acrida cinerea lacks stridulatory organs on its legs and so they do not make noise while moving.
Acrida cinerea, like other Acrida species, is a pest of many agricultural crops. It is found throughout China, Korea, Japan, South East Asia and Indonesia. Historically it has been used as a human food source, and it has been investigated for its nutritional value for the poultry industry. Wikipedia →

Rare
Under 5% of wildlife watchers report an Oriental Longheaded Locust sighting in Shanghai on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 185th most-seen of the 215 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.
July and August
In those months about 10% of wildlife watchers report an Oriental Longheaded Locust in Shanghai on a given day, against under 5% in September to June, the lowest months. Those are among Shanghai's wettest months, with about 160 mm of rain a month against 55 mm in December.
14th of 15
Of the 15 cities where we can rate Oriental Longheaded Locust sightings, Shanghai ranks 14th at under 5%. The best odds are in Nagoya (Japan, about 40%), Daejeon (South Korea, about 30%) and Daegu (South Korea, about 30%).
GBIF citizen-science records
It is estimated from how often the Oriental Longheaded Locust is recorded against all the insects logged in Shanghai (6 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.
