With luck
About 10% of wildlife watchers report a Red-Necked Cane Borer sighting in Boston on a given day, based on 98 verified sightings from GBIF citizen-science data. It is the 165th most-seen of the 1200 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Red-Necked Cane Borer is recorded against all the insects logged in Boston (98 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.
