Rare
Under 5% of wildlife watchers report an Early Tachinid Fly sighting in Boston on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 668th 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 20%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Early Tachinid Fly is recorded against all the insects logged in Boston (13 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.
