Velarifictorus micado
In 3 days ~20% in a week ~40%
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 →

GBIF citizen-science records
It is estimated from how often the Japanese Burrowing Cricket is recorded against all the insects logged in Hangzhou (10 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.
