Amphipyra pyramidea
In 3 days ~10% in a week ~20%
The copper underwing, humped green fruitworm or pyramidal green fruitworm (Amphipyra pyramidea) is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
This species can be found across the Palaearctic region including Europe, North Africa, the Near East, Iran, southern Siberia, northern India, Korea and Japan. It is rather common over the southern half of Britain. This species has a wingspan of 47–54 mm, the female usually slightly larger than the male. The forewings are brown marked with paler fascia and a pale, dark-centred stigma. The hindwings are a rich bright copper colour (hence the common name of "copper underwing").
It is very similar to Svensson's copper underwing (Amphipyra berbera) but identification is usually fairly straightforward by looking at some markings on the forewings, the detail of the labial palps and at the underside of the hindwings. This species has a pale area in the centre of the hindwings, contrasting with much darker marginal areas, while in A. berbera the whole underwing is more or less uniform in colour.

Rare
Under 5% of wildlife watchers report a Eurasian Copper Underwing sighting in Pyrénées National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 869th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April and August
In those months about 10% of wildlife watchers report a Eurasian Copper Underwing in Pyrénées National Park on a given day, against under 5% in May–July and September–March, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Eurasian Copper Underwing sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
3rd of 3
Of the 3 parks where we can rate Eurasian Copper Underwing sightings, Pyrénées National Park ranks 3rd at under 5%. The best odds are in Bavarian Forest National Park (Germany, about 10%) and Wadden Sea National Park (Germany, under 5%).
GBIF citizen-science records
It is estimated from how often the Eurasian Copper Underwing is recorded against all the insects logged in Pyrénées National Park (9 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.
