With luck
About 10% of wildlife watchers report a Shaded Fan-Foot sighting in Porto on a given day, based on 47 verified sightings from GBIF citizen-science data. It is the 134th most-seen of the 498 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Shaded Fan-Foot is recorded against all the insects logged in Porto (47 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.
