Rare
Under 5% of wildlife watchers report a Rose Curculio sighting in Boston on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 1063rd 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Rose Curculio in Boston on a given day, so our monthly data shows no clear season.
Among the best
Of the 4 cities where we can rate Rose Curculio sightings, Boston ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Edmonton (Canada, under 5%) and Toronto (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Rose Curculio is recorded against all the insects logged in Boston (7 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.
