Noctua pronuba (NL: Huismoeder - Ei/ EN: Large Yellow Underwing - Egg / DE: Hausmutter - Ei / FR: Fiancée - Œuf) is a moth, the type species for the family Noctuidae. It is an abundant species throughout Europe, one of the most common and most familiar moths of the region. In some years the species is highly migratory with large numbers appearing suddenly in marginal parts of the range. It flies from July to September and is freely attracted to light. The species occupies a range of habitats, and the caterpillars feed on a variety of herbaceous plants and grasses. Eggs are deposited in large groups on the stems of all kinds of plant species (like the blade of grass in the image). The egg is nearly spherical, slightly flattened towards the base. It measures 0.45 mm in height and 0.5 mm in diameter. In the lower half the surface is smooth, in the upper half it has slightly raised longitudinal ribs. They are crossed by very faint transverse ribs.
