The gatekeeper or hedge brown (Pyronia tithonus) is a species of butterfly found across Europe. Given its preference for warmer weather, the restriction of range expansion can be assumed to be due to climate. Colonies vary in size depending on the available habitat, and can range from a few dozen to several thousand butterflies. Named for its rigorous patrol of hedges and woodland rides, the gatekeeper butterfly is a prime pollinator. The caterpillars primarily feed on fine grasses such as fescues (Festuca) and bents (Agrostis), which are common in meadows and roadside verges.
It is a member of the subfamily Satyrinae in the family Nymphalidae. A similar species is the meadow brown; the two species can be difficult to distinguish with closed wings, since the underwing markings are very similar. However, the gatekeeper tends to rest with its wings open, whereas the meadow brown usually rests with its wings closed. The gatekeeper is also smaller and more orange than the meadow brown and has double pupils on its eyespots.
Two other similar species of Pyronia are found in southern Europe, the southern gatekeeper (P. cecilia) and the Spanish gatekeeper... Wikipedia →

Possible
About 20% of wildlife watchers report a Gatekeeper sighting in Snowdonia National Park on a given day, based on 41 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 38th most-seen of the 387 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.
July and August
In those months about 40% of wildlife watchers report a Gatekeeper in Snowdonia National Park on a given day, against under 5% in September to June, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Gatekeeper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 8
Of the 8 parks where we can rate Gatekeeper sightings, Snowdonia National Park ranks 4th at about 20%. The best odds are in Picos de Europa National Park (Spain, about 30%), Aigüestortes National Park (Spain, about 30%) and Ordesa y Monte Perdido National Park (Spain, about 20%).
Same family: Nymphalidae
The closest relatives of the Gatekeeper that you can see in Snowdonia National Park (family Nymphalidae, Brush-footed Butterflies) are Speckled Wood (about 40%), Red Admiral (about 30%) and European Peacock Butterfly (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gatekeeper is recorded against all the insects logged in Snowdonia National Park (41 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.
