Velarifictorus micado
In 3 days ~20% in a week ~50%
Velarifictorus micado, the Japanese burrowing cricket, is a cricket in the subfamily Gryllinae (family Gryllidae). It is found in southern Asia, along with an introduced population in the United States. It was first reported in the US in 1959, likely as overwintering eggs in the soil of imported plants, and has since spread all throughout the eastern half of the country. V. micado is considered to be quite passive and non-destructive. Studies have shown that its range has spread northward and may be much more invasive than previously thought. Wikipedia →

With luck
About 10% of wildlife watchers report a Japanese Burrowing Cricket sighting in Shanghai on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 61st most-seen of the 215 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
August and September
In those months about 20% of wildlife watchers report a Japanese Burrowing Cricket in Shanghai on a given day, against under 5% in October 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.
4th of 17
Of the 17 cities where we can rate Japanese Burrowing Cricket sightings, Shanghai ranks 4th at about 10%. The best odds are in Shenyang (China, about 30%), Nagoya (Japan, about 20%) and Beijing (China, about 10%).
Same family: Gryllidae
The closest relatives of the Japanese Burrowing Cricket that you can see in Shanghai (family Gryllidae, True Crickets) are Emma Field Cricket (about 10%), Loxoblemmus doenitzi (about 10%) and Loxoblemmus equestris (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Japanese Burrowing Cricket is recorded against all the insects logged in Shanghai (28 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.
