The cinnabar moth (Tyria jacobaeae) is a brightly coloured Arctiinae moth found as a native species in Europe and western and central Asia then east across the Palearctic to Siberia to China. It has been introduced into New Zealand, Australia and North America to control ragwort, on which its larvae feed, as a result of this diet the Cinnabar larvae and adult is poisonous to most of its natural predators, its red coloration acting to signal this to predators (Aposematism).
The moth is named after the red mineral cinnabar because of the red patches on its predominantly black wings. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. Cinnabar moths are about 20 mm (0.79 in) long and have a wingspan of 34–46 mm (1.3–1.8 in).
While generally nocturnal, the species is also often spotted in daylight hours. Cinnabar moths are day-flying insects with distinctive pinkish-red and black wings. There is little variation in patterning, although on rare occasions the red markings may be replaced with yellow, or the forewing is entirely red with a black border, or the wings are completely black.

With luck
About 10% of wildlife watchers report a Cinnabar Moth sighting in Prague on a given day, based on 46 verified sightings from GBIF citizen-science data. It is the 131st most-seen of the 724 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June and July
In those months about 10% of wildlife watchers report a Cinnabar Moth in Prague on a given day, against under 5% in August to May, the lowest months. Those are among Prague's wettest months, with about 80 mm of rain a month against 30 mm in February.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Cinnabar Moth sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
15th of 18
Of the 18 cities where we can rate Cinnabar Moth sightings, Prague ranks 15th at about 10%. The best odds are in Liverpool (United Kingdom, about 40%), Manchester (United Kingdom, about 40%) and Birmingham (United Kingdom, about 30%).
Same family: Erebidae
The closest relatives of the Cinnabar Moth that you can see in Prague (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Jersey Tiger (about 10%), Burnet Companion (about 10%) and Spongy Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cinnabar Moth is recorded against all the insects logged in Prague (46 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.
