About the Lychnis
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.

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 →
