Acrida cinerea
In 3 days ~70% in a week ~90%
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 →

Possible
About 30% of wildlife watchers report an Oriental Longheaded Locust sighting in Daejeon on a given day, based on 38 verified sightings from GBIF citizen-science data. It is the 4th most-seen of the 53 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
July
In that month about 60% of wildlife watchers report an Oriental Longheaded Locust in Daejeon on a given day, against under 5% in March–May, October and December–January, the lowest months. That is one of Daejeon's wettest months, with about 320 mm of rain against 25 mm in January.
2nd of 15
Of the 15 cities where we can rate Oriental Longheaded Locust sightings, Daejeon ranks 2nd at about 30%. The best odds are in Nagoya (Japan, about 40%).
Same family: Acrididae
The closest relatives of the Oriental Longheaded Locust that you can see in Daejeon (family Acrididae, Short-horned Grasshoppers) are Carinate Locust (about 20%) 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 Daejeon (38 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.
