Velarifictorus micado
In 3 days ~10% in a week ~20%
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 →

Rare
Under 5% of wildlife watchers report a Japanese Burrowing Cricket sighting in Taipei on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 570th most-seen of the 765 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.
November
In that month about 10% of wildlife watchers report a Japanese Burrowing Cricket in Taipei on a given day, against under 5% in December to October, the lowest months.

GBIF citizen-science records
It is estimated from how often the Japanese Burrowing Cricket is recorded against all the insects logged in Taipei (8 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.
