With luck
About 10% of wildlife watchers report a Chestnut Longhorn Beetle sighting in Boston on a given day, based on 56 verified sightings from GBIF citizen-science data. It is the 244th most-seen of the 1200 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Chestnut Longhorn Beetle in Boston on a given day, against under 5% in August to June, the lowest months.

Only Boston, in our data

GBIF citizen-science records
It is estimated from how often the Chestnut Longhorn Beetle is recorded against all the insects logged in Boston (56 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.
