Sideridis rivularis, the campion, is a species of moth of the family Noctuidae. It is found in from the northern part of the Iberian Peninsula, through the whole of Europe. To the east, it is found in Central Asia and Siberia, up to Manchuria. To the south, it is found in the Mediterranean Sea region (with the exception of Greece) and parts of Asia Minor. In the Alps, it is found at up to 1,600 metres above sea level.
The wingspan is 27–30 mm. The length of the forewings is 14–16 mm. Forewing brownish fuscous with a violet sheen; the lines double; claviform stigma large, black; orbicular and reniform grey with yellowish or whitish outlines, conversely oblique and contiguous on median vein; veins dark outlined with grey; submarginal line yellowish or white, dentate; hindwing brownish fuscous, darker in female: the ab. behenis Frr. has the outer half of costa of forewing pale; — S. mandarina Leech (now considered to be a species) from Japan and China, is rather larger and darker, the markings in consequence somewhat less distinct.
The moth flies from April to September depending on the location. There are two generations per year... Wikipedia →

Rare
Under 5% of wildlife watchers report a Campion sighting in London on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 673rd most-seen of the 1504 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.
July
In that month about 10% of wildlife watchers report a Campion in London on a given day, against under 5% in August to June, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Campion sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
2nd of 3
Of the 3 cities where we can rate Campion sightings, London ranks 2nd at under 5%. The best odds are in Liverpool (United Kingdom, about 10%).
Same family: Noctuidae
The closest relatives of the Campion that you can see in London (family Noctuidae, Cutworm Moths and Allies) are Large Yellow Underwing (about 30%), Heart And Dart (about 20%) and Shuttle-Shaped Dart (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Campion is recorded against all the insects logged in London (27 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.
