Anoplophora chinensis
In 3 days ~20% in a week ~30%
Anoplophora chinensis, the citrus long-horned beetle (also appearing in many sources as Anoplophora malasiaca), is a long-horned beetle native to Japan, China, Korea, Taiwan and Southeast Asia where it is considered a serious pest. This beetle has invaded several countries in Europe, including Italy, Switzerland, Turkey, France, Germany, and Croatia.
Infestations by the beetle can kill many different types of hardwood trees including Citrus, pecan, apple, Australian pine, Hibiscus, sycamore, willow, pear, mulberry, chinaberry, poplar, Litchi, kumquat, Japanese red cedar, oak, and Ficus.
Anoplophora chinensis is native to most parts of China and Korea, as well as Vietnam, Malaysia, Indonesia, and the Philippines. However, this beetle is characterized as an invasive species in many parts of the world, including countries in Europe such as Italy, as it has been able to be transported to additional geographic regions by burrowing into shipments from Asia to countries in Europe. It makes its way into shipments that contain plants or wood and burrows into them.
The citrus long-horned beetle was first discovered in the U.S. in April 1999... Wikipedia →

With luck
About 10% of wildlife watchers report a Citrus Longhorn Beetle sighting in Taipei on a given day, based on 45 verified sightings from GBIF citizen-science data. It is the 221st most-seen of the 765 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
April to July
In those months about 10% of wildlife watchers report a Citrus Longhorn Beetle in Taipei on a given day, against under 5% in August to March, the lowest months.
24th of 26
Of the 26 cities where we can rate Citrus Longhorn Beetle sightings, Taipei ranks 24th at about 10%. The best odds are in Guiyang (China, about 30%), Xi'an (China, about 30%) and Nagoya (Japan, about 20%).
GBIF citizen-science records
It is estimated from how often the Citrus Longhorn Beetle is recorded against all the insects logged in Taipei (45 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.
