About Mythimna ferrago Fabricius, 1787
Technical description and variation: The wingspan of Mythimna ferrago ranges from 36 to 44 mm. The forewing is pale greyish rufous, speckled with dark markings; the dark grey lines are indistinct. The outer line is regularly lunulate-dentate, with the teeth marked by black dashes on the veins. The reniform stigma is obscure, ending in a cloudy pale spot at the lower end of the cell. The hindwing is greyish ochreous, and the ventral tufts are black. This species varies in coloration: ferrago F. is the reddest form; grisea Haw is grey with no rufous admixture, and generally has clearer markings; fulvescens Tutt is a rare form that is fulvous instead of red; ab. marginata Tutt has silvery grey hindwings with a broad dark border.
