Eupsilia transversa, the satellite, is a moth of the family Noctuidae. The species was first described by Johann Siegfried Hufnagel in 1766. It is distributed throughout the Palearctic. The moth has variable wing patterns, with a wingspan of 32-42mm.
The common name derives from the contrasting dots on each wing, ranging in colour from white or yellow to red, which has two smaller spots close to it, appearing to be in orbit. The hindwings are brown with a paler fringe.
Forewing grey brown, with deeper suffusion; inner and outer lines fine, and more or less erect, the inner straight, the outer waved; a bent median shade, one before the inner line, and another close beyond the outer; submarginal line pale, interrupted, preceded and followed by dark shades; claviform and orbicular stigmata obsolete; reniform in the type form orange yellow, with a white dot above and below it; fringe concolorous, preceded by pale marginal lunules; hindwing fuscous brown. Linne's type form, showing a yellow reniform with two white dots, especially in combination with the grey-brown ground colour, is decidedly rare; as a rule, when the reniform... Wikipedia →

Rare
Under 5% of wildlife watchers report a The Satellite sighting in London on a given day, based on 25 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.
February–March and November
In those months about 10% of wildlife watchers report a The Satellite in London on a given day, against under 5% in April–October and December–January, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most The Satellite sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
8th of 11
Of the 11 cities where we can rate The Satellite sightings, London ranks 8th at under 5%. The best odds are in Kharkiv (Ukraine, about 10%), Vienna (Austria, about 10%) and Prague (Czechia, about 10%).
Same family: Noctuidae
The closest relatives of the The Satellite 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 The Satellite is recorded against all the insects logged in London (25 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.
