Orthonama obstipata, the gem, is a moth of the family Geometridae. The species was first described by Johan Christian Fabricius in 1794. It is common in continental Europe and adjacent lands, though in the northeast, its range does not significantly extend beyond the Baltic region and it is absent from northern Russia. This well-flying species is somewhat prone to vagrancy and able to cross considerable distances of open sea; it can thus be regularly found on the British Isles and even on Iceland.
