Sideridis reticulata

Sideridis reticulata, the bordered Gothic, is a noctuid moth with a wide Palearctic range. It is recorded from the Iberian Peninsula through Europe and the temperate parts of Central Asia to the Russian Far East, reaching Fennoscandia south of the Arctic Circle in the north and the Mediterranean in the south, and in the Alps it rises above 2,000 metres. The wingspan is 32 to 37 millimetres. The forewing is dark fuscous with a purplish sheen when fresh, with white veins, a broad black claviform stigma and a white submarginal line, and the hindwing is fuscous and paler toward the base, especially in males. Adults fly from May to August depending on the location. The larva is greenish or pinkish ochreous, speckled with darker tones, and feeds on Saponaria officinalis, Silene vulgaris and Polygonum aviculare. The species has disappeared as a resident from the United Kingdom during the first decade of the twenty-first century.
