About Charanyca ferruginea (Esper, 1785)
The brown rustic moth, whose currently accepted scientific name is Charanyca ferruginea (Esper, 1785) and was formerly classified as Rusina ferruginea, is a member of the Noctuidae moth family. It is distributed across Europe, extending eastward through the Palearctic region to the Sayan Mountains in Central Asia. This moth has a wingspan of 32 to 40 millimeters. Its forewings have a dark brown base colour, with a series of small white marks running along the costa. The stigmata on the forewings are not well defined. The antemedian line runs obliquely outward from the costa and is darker than the forewing ground colour. Both the fine postmedian line and the irregular, dark subterminal line are also darker than the forewing ground colour. The hindwings are yellow-brown, with darker veins and a small discal spot. Fully grown caterpillars have a reddish-brown base body colour. They have a very narrow yellow-white dorsal line, with similarly narrow, distinct secondary dorsal lines. Blackish slashes are present on the posterior segments of the body. The caterpillar's lateral stripe is grey-brown, its stigma is black, and its head is dark brown. Adult moths fly from June to July, with the exact timing varying by location. The larvae feed on a variety of herbaceous plants, including species in the Rumex genus.
