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 →

Under 5% of wildlife watchers report a Lydd Beauty sighting in Lisbon on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 256th most-seen of the 441 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.
May and October
In those months about 10% of wildlife watchers report a Lydd Beauty in Lisbon on a given day, against under 5% in June–September and November–April, the lowest months.

GBIF citizen-science records
It is estimated from how often the Lydd Beauty is recorded against all the insects logged in Lisbon (11 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.
