Under 5% of wildlife watchers report a Grass Eggar sighting in Lisbon on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 136th most-seen of the 441 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Grass Eggar is recorded against all the insects logged in Lisbon (25 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.
