Rare
Under 5% of wildlife watchers report a Red-Winged Longhorn Beetle sighting in Boston on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 583rd 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.
July
In that month about 10% of wildlife watchers report a Red-Winged Longhorn Beetle in Boston on a given day, against under 5% in August to June, the lowest months.
Only Boston, in our data
Boston is the only city on Wallace's Line with enough records to rate Red-Winged Longhorn Beetle sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Cerambycidae
The closest relatives of the Red-Winged Longhorn Beetle that you can see in Boston (family Cerambycidae, Longhorn Beetles) are Locust Borer (about 20%), Red Milkweed Beetle (about 20%) and Banded Longhorn Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-Winged Longhorn Beetle is recorded against all the insects logged in Boston (15 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.
