SPECIES COMPARISON - OPEROPHTERA SP.

Winter Moth (Operophtera brumata) / Northern Winter Moth (O. fagata)

(Left) Northern Winter Moth (O.fagata) (Right) Winter Moth (O.brumata)

When seen side by side, the size difference between the two species is obvious. The two species show no overlap in wingspan, 32-40mm for fagata and 22-28mm for brumata. O.fagata has pale, off-white hindwings, whereas O.brumata is generally a darker, browner and stronger-marked species, although as the individual illustrated here demonstrates, coloration does vary.
