Oligia

A genus of moths in the Noctuidae family. These are small to medium-sized moths that are typically cryptic in coloration, browns, grays, and blackish tones, often with subtle banding and shading that help them blend into bark or leaf litter. The forewings are usually narrow and patterned with indistinct wavy or mottled lines, while hindwings are paler, often grayish or whitish with darker veins or fringes. The larvae generally feed on grasses (Poaceae), especially within the stems, and some species can be minor pests in pasture or cereal crops. The species O. strigilis, O. versicolor, and O. latruncula are notoriously hard to separate by wing pattern alone, often requiring dissection for confident ID.
