Rare
Under 5% of wildlife watchers report a Catocala optata sighting in Porto on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 342nd 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 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Catocala optata in Porto on a given day, against under 5% in September to June, the lowest months. Those are among Porto's driest months, with about 20 mm of rain a month against 140 mm in January.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Catocala optata sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Porto, in our data
Porto is the only city on Wallace's Line with enough records to rate Catocala optata sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Catocala
The closest relatives of the Catocala optata that you can see in Porto (genus Catocala, Underwing Moths) are French Red Underwing (about 10%) and Minsmere Crimson Underwing (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Catocala optata is recorded against all the insects logged in Porto (10 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.
