Phyllopertha horticola, the garden chafer or garden foliage beetle, is a beetle from the family Scarabaeidae. Phyllopertha horticola was described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. Phyllopertha horticola var. ustulatipennis A. Villa & G. B. Villa, 1833
This rather common species is widely widespread in Europe and in Asia, east to Siberia and Mongolia. In the north of Europe their distribution reaches the middle Fennoscandia and includes the British Isles, in southern Europe it mainly occurs in the mountains. It is the only European representative of the genus Phyllopertha.
These beetles inhabit bushes, hedgerows, woodland edges, meadows and fields, from the lowlands to mountainous areas. They also live in parks and gardens, hence the common name of garden chafer. Phyllopertha horticola is approximately 8.5–11 millimetres (0.33–0.43 in) in size. Unlike Mimela of the same family, these beetles have a non-ovoid body. They have chestnut-brown wing casings which are covered with a long upright pubescence. On each elytron run six longitudinal bands of small dots. Head and thorax are finely... Wikipedia →

Possible
About 30% of wildlife watchers report a Garden Chafer sighting in Snowdonia National Park on a given day, based on 58 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 14th most-seen of the 387 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
June
In that month about 50% of wildlife watchers report a Garden Chafer in Snowdonia National Park on a given day, against under 5% in August to April, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Garden Chafer 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 11 parks where we can rate Garden Chafer sightings, Snowdonia National Park has the highest daily chance: about 30%. Next come Hohe Tauern National Park (Austria, about 20%) and Vanoise National Park (France, about 20%).
Same family: Scarabaeidae
The closest relatives of the Garden Chafer that you can see in Snowdonia National Park (family Scarabaeidae, Scarabs) are Common Cockchafer (about 20%), Dune Chafer (about 10%) and Aegialia arenaria (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Garden Chafer is recorded against all the insects logged in Snowdonia National Park (58 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.
