It flies in a variety of grassy habitats, including roadsides, woodland edges and clearings, prairies, bogs, and arctic and alpine taiga and tundra. It is a poor flyer, but can sometimes be found along ditches seeking new grounds. It is a holarctic species found in northern Europe, east across the Palearctic and across North America. The species was first described by Otto Friedrich Müller in 1764.
Successful reintroductions of the species to North West England took place in 2020, 2022 and 2023. C. tiphon Rott. (— davus F., tullia Hbn.) (48h).

Possible
About 30% of wildlife watchers report a Large Heath sighting in Wrangell-St. Elias National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 27 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Large Heath in Wrangell-St. Elias National Park on a given day, against under 5% in May and June, the lowest months. October to March have too few records to rate.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Large Heath 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 3 parks where we can rate Large Heath sightings, Wrangell-St. Elias National Park has the highest daily chance: about 30%. Next come Denali National Park (United States, about 20%) and Cairngorms National Park (United Kingdom, about 10%).
Same family: Nymphalidae
The closest relatives of the Large Heath that you can see in Wrangell-St. Elias National Park (family Nymphalidae, Brush-footed Butterflies) are Alaskan Fritillary (about 40%), White-Veined Arctic (about 40%) and Mormon Fritillary (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Large Heath is recorded against all the insects logged in Wrangell-St. Elias National Park (10 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.
