The lychnis (Hadena bicruris) is a moth of the family Noctuidae. It is found in northern and western Europe and Turkey. It has an Atlantic-Mediterranean distribution. In the East Palearctic it is replaced by Hadena capsincola.
This species has dark brown forewings marked with two prominent white-bordered stigmata and a white subterminal line. The hindwings are buffish, darkening to brown towards the margin but with a prominent white fringe. Seitz states - Distinguished from rivularis F. by the absence of the violet sheen; the markings white instead of yellow; the upper stigmata not conjoined; a conspicuous black blotch above inner margin near base; hindwing fuscous. Larva dull brown, with darker dorsal line and oblique subdorsal streaks.
Hadena capsincola has only been listed as an independent species since 1996 after a reworking of the genus Hadena by Hacker. While H. bicruris is mainly native to Western Europe, H. capsincola is found in eastern regions. It is usually a little darker in colour. However, only a genital morphological examination will distinguish them reliably.
Hadena perplexa is mainly distinguished by the absence of the blackish... Wikipedia →

Rare
Under 5% of wildlife watchers report a Lychnis sighting in London on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 1005th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Lychnis in London on a given day, so our monthly data shows no clear season.
3rd of 3
Of the 3 cities where we can rate Lychnis sightings, London ranks 3rd at under 5%. The best odds are in Liverpool (United Kingdom, about 10%) and Manchester (United Kingdom, about 10%).
Same family: Noctuidae
The closest relatives of the Lychnis 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 Lychnis is recorded against all the insects logged in London (11 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.
