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 Hong Kong on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 868th most-seen of the 1125 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.
September and October
In those months about 10% of wildlife watchers report an Oriental Longheaded Locust in Hong Kong on a given day, against under 5% in November to August, the lowest months.
15th of 15
Of the 15 cities where we can rate Oriental Longheaded Locust sightings, Hong Kong ranks 15th at under 5%. 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 Hong Kong (family Acrididae, Short-horned Grasshoppers) are Carinate Locust (about 10%), Ceracris nigricornis (about 10%) and Short-Winged Rice 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 Hong Kong (7 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.
