Blood-vein

The blood-vein (Timandra comae) is a moth of the family Geometridae. The species was first described by Anton Schmidt in 1931.

==Distribution== It has a scattered distribution in western and central Europe north of the Alps. In the British Isles the distribution is patchy outside southern England and Wales. In far eastern Europe – east of a line running roughly from Finland through Estonia – it is replaced by its sister species Timandra griseata. The species were split in 1931, only to be subsequently re-merged by most authors. But since 1994, new research has come out in favour of treating them as distinct species.
