Peribatodes ilicaria, the Lydd beauty, is a moth of the family Geometridae. The species was first described by Carl Geyer in 1833. It can be found in Europe and North Africa. The wingspan is about 30 mm. Peribatodes ilicaria is difficult to certainly distinguish from its congeners. See Townsend et al.
The moths fly from July to September depending on the location. The larvae feed on various trees and shrubs. Wikipedia →

With luck
About 10% of wildlife watchers report a Lydd Beauty sighting in Porto on a given day, based on 129 verified sightings from GBIF citizen-science data. It is the 29th most-seen of the 498 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September
In that month about 30% of wildlife watchers report a Lydd Beauty in Porto on a given day, against under 5% in November to March, the lowest months. That is one of Porto's driest months, with about 50 mm of rain against 140 mm in January.

Across all the parks we cover, that three-hour window holds the most Lydd Beauty sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.

Of the 2 cities where we can rate Lydd Beauty sightings, Porto has the highest daily chance: about 10%. Next come Lisbon (Portugal, under 5%).
GBIF citizen-science records
It is estimated from how often the Lydd Beauty is recorded against all the insects logged in Porto (129 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.
