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.

With luck
About 10% of wildlife watchers report a Eurasian Copper Underwing sighting in Copenhagen on a given day, based on 45 verified sightings from GBIF citizen-science data. It is the 86th most-seen of the 476 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Eurasian Copper Underwing in Copenhagen on a given day, against under 5% in November to June, the lowest months. That is one of Copenhagen's wettest months, with about 85 mm of rain against 35 mm in April.
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.
Among the best
Of the 19 cities where we can rate Eurasian Copper Underwing sightings, Copenhagen ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Liverpool (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Eurasian Copper Underwing is recorded against all the insects logged in Copenhagen (45 verified sightings), 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.
