Psodos quadrifaria is a moth of the family Geometridae first described by Johann Heinrich Sulzer in 1776. It is found in the higher parts of the Alps, as well as the Pyrenees, the High Tatras and the Balkan Mountains. It also has a scattered distribution in the Giant Mountains. Psodos quadrifaria is found at heights of up to 2,700 metres.
The wingspan is 18–25 mm. Adults are on wing from the end of May to mid-August and are day active. There is one generation per year. The larvae feed on the leaves of various low-growing plants. Wikipedia →

Possible
About 20% of wildlife watchers report a Psodos quadrifaria sighting in Aigüestortes National Park on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 62nd most-seen of the 256 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Psodos quadrifaria is recorded against all the insects logged in Aigüestortes National Park (19 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.
