Craniophora ligustri, the coronet, is a moth of the family Noctuidae. The species was first described by Michael Denis and Ignaz Schiffermüller in 1775. It is found in Europe, through the Palearctic to Japan. It is found from western and central Europe to the Russian Far East, northern China, Japan and Korea. In the north, the range extends to southern Scandinavia, the Baltic States and central Russia (approximately north to Saint Petersburg) as well as Ukraine. However, on the Iberian Peninsula, the species is limited to the north. In the eastern Mediterranean, it reaches northern Greece with smaller isolated occurrence in central Greece and the Peloponnese. The distribution area also includes Israel, Asia Minor and the Caucasus. It occurs in Cyprus.
The wingspan is 30–35 mm. Its forewings are purplish fuscous, more or less greenish tinged, with a paler patch beyond the cell; prothorax conspicuously whitish. — ab. sundevalli Lampa is a form in which both forewing and thorax are entirely dark olive green. ab. nigra Tutt has the forewing black throughout, without any green tinge, and has only been taken in the North of England; lastly, in ab. coronula...

Rare
Under 5% of wildlife watchers report a Coronet sighting in Prague on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 505th most-seen of the 724 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.
August
In that month about 10% of wildlife watchers report a Coronet in Prague on a given day, against under 5% in September to July, the lowest months. That is one of Prague's wettest months, with about 80 mm of rain against 30 mm in February.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Coronet sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
9th of 9
Of the 9 cities where we can rate Coronet sightings, Prague ranks 9th at under 5%. The best odds are in Birmingham (United Kingdom, about 10%), Essen (Germany, about 10%) and London (United Kingdom, about 10%).
Same family: Noctuidae
The closest relatives of the Coronet that you can see in Prague (family Noctuidae, Cutworm Moths and Allies) are Silver Υ (about 10%), Large Yellow Underwing (about 10%) and Knot Grass Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Coronet is recorded against all the insects logged in Prague (8 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.
