Under 5% of wildlife watchers report a Pale Tussock Moth sighting in Saint Petersburg on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 295th most-seen of the 448 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.
September
In that month about 10% of wildlife watchers report a Pale Tussock Moth in Saint Petersburg on a given day, against under 5% in October to August, the lowest months.

GBIF citizen-science records
It is estimated from how often the Pale Tussock Moth is recorded against all the insects logged in Saint Petersburg (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.
