Rare
Under 5% of wildlife watchers report a Twin-Barred Knot-Horn sighting in Porto on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 395th 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 to August
In those months about 10% of wildlife watchers report a Twin-Barred Knot-Horn in Porto on a given day, against under 5% in September to May, the lowest months. Those are among Porto's driest months, with about 20 mm of rain a month against 140 mm in January.

GBIF citizen-science records
It is estimated from how often the Twin-Barred Knot-Horn is recorded against all the insects logged in Porto (9 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.
