Under 5% of wildlife watchers report a Silvered Brown Veneer sighting in Porto on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 422nd most-seen of the 498 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.
June and August
In those months about 10% of wildlife watchers report a Silvered Brown Veneer in Porto on a given day, against under 5% in July and September–May, the lowest months. Those are among Porto's driest months, with about 25 mm of rain a month against 140 mm in January.

GBIF citizen-science records
It is estimated from how often the Silvered Brown Veneer is recorded against all the insects logged in Porto (6 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.
