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 Taichung on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 144th most-seen of the 197 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.
November and December
In those months about 20% of wildlife watchers report an Oriental Longheaded Locust in Taichung on a given day, against under 5% in January–April and June–August, the lowest months. Those are among Taichung's driest months, with about 45 mm of rain a month against 330 mm in August.
10th of 15

GBIF citizen-science records
It is estimated from how often the Oriental Longheaded Locust is recorded against all the insects logged in Taichung (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.
