Possible
About 20% of wildlife watchers report a Lythria cruentaria sighting in Sierra Nevada National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 113th most-seen of the 479 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.
May and June
In those months about 30% of wildlife watchers report a Lythria cruentaria in Sierra Nevada National Park on a given day, against under 5% in August to April, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Lythria cruentaria sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 parks where we can rate Lythria cruentaria sightings, Sierra Nevada National Park has the highest daily chance: about 20%. Next come Sierra de Guadarrama National Park (Spain, about 10%) and Wadden Sea National Park (Germany, about 10%).
Same family: Geometridae
The closest relatives of the Lythria cruentaria that you can see in Sierra Nevada National Park (family Geometridae, Geometer Moths) are Vestal (about 20%), Idaea sericeata (about 20%) and Yellow Shell Moth (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lythria cruentaria is recorded against all the insects logged in Sierra Nevada National Park (15 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.
