Any time of year
In every month with enough records, under 5% of wildlife watchers report a Red-Shouldered Bostrichid 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 Red-Shouldered Bostrichid is recorded against all the insects logged in Washington (11 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.
