Rare
Under 5% of wildlife watchers report a Lydd Beauty sighting in Sierra de Guadarrama National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 473rd most-seen of the 597 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 September
In those months about 10% of wildlife watchers report a Lydd Beauty in Sierra de Guadarrama National Park on a given day, against under 5% in July–August and October–May, the lowest months.
Between 10 pm and 1 am
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.
4th of 5
Of the 5 parks where we can rate Lydd Beauty sightings, Sierra de Guadarrama National Park ranks 4th at under 5%. The best odds are in Monfragüe National Park (Spain, about 10%), Doñana National Park (Spain, about 10%) and Cévennes National Park (France, about 10%).
GBIF citizen-science records
It is estimated from how often the Lydd Beauty is recorded against all the insects logged in Sierra de Guadarrama National Park (6 verified sightings from 2019 to 2026), 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.
