Rare
Under 5% of wildlife watchers report an Orange-Backed Calligrapher sighting in Washington on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 1025th most-seen of the 1807 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 an Orange-Backed Calligrapher in Washington on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Orange-Backed Calligrapher is recorded against all the insects logged in Washington (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.
