Acrida cinerea
In 3 days ~20% in a week ~40%
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 →

With luck
About 10% of wildlife watchers report an Oriental Longheaded Locust sighting in Beijing on a given day, based on 37 verified sightings from GBIF citizen-science data. It is the 90th most-seen of the 401 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report an Oriental Longheaded Locust in Beijing on a given day, against under 5% in September to May, the lowest months. That is one of Beijing's wettest months, with about 110 mm of rain against almost none in January.
11th of 15
Of the 15 cities where we can rate Oriental Longheaded Locust sightings, Beijing ranks 11th at about 10%. The best odds are in Nagoya (Japan, about 40%), Daejeon (South Korea, about 30%) and Daegu (South Korea, about 30%).
Same family: Acrididae
The closest relatives of the Oriental Longheaded Locust that you can see in Beijing (family Acrididae, Short-horned Grasshoppers) are Carinate Locust (about 10%), Large Green Grasshopper (about 10%) and Slender Green-Winged Grasshopper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Oriental Longheaded Locust is recorded against all the insects logged in Beijing (37 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.
