Amoncr the more common Noctuids that occur in our meadows and pastures, and that fly up before us as we walk through them, are two species belonging to the genus Dras- teria (Dras-te'ri-a). These may be called the Clover Looping- owlets; for the larvae feed on the leaves of clover, and, as they have only three pairs of prolegs, they walk in a loop- ing manner like the Geometrids. One of these species is Drasteria erechtea (D. e-rech'te-a). This moth (Fig. 357) has dark or light drab-gray fore wings, which are marked by two large dark bands, as shown in the figure. These bands are always separate, dis- Yig. ^^T.—Dr aster ia erechtea. tinct, and well defined towards the inner margin in the male; in the female the markings are much less dis- tinct. The other common species of this genus is Drasteria eras- siuscula (D. cras-si-us^cu-la). In this species the fore wings have either a distinct violaceous brown or a red shade, with the two large dark bands very variable, often shading into the ground-color on the outer edge or coalescing near the inner margin ; all the markings are equally distinct in both sexes. There is a group of Noctuids containing about a score of genera in which the species differ markedly in appearance from the majority of the members of the family. In this group the moths are of small or moderate size ; and some of them bear a strong resemblance to Tortricids. Many of the species are marked with bright colors, and especially with white.
