About Pempelia ornatella (Denis & Schiffermüller), 1775
Pempeliella ornatella is a moth species in the Pyralidae family, first described by Michael Denis and Ignaz Schiffermüller in 1775, with the scientific name Pempelia ornatella (Denis & Schiffermüller), 1775. This species is distributed across most of Europe, extending eastward to the Ural Mountains, Siberia, central Yakutia, and Kyrgyzstan. It has a wingspan that measures between 23 and 27 millimetres (0.91 to 1.06 inches). Its forewings are brownish ochreous. The veins and costa are suffused with fuscous colouring, and have some white mixed in. The forewing lines are whitish: the first line is interrupted, and is edged posteriorly with dark spots on the veins, while the second line is almost straight. There are two dark fuscous discal dots placed transversely, each with diffuse whitish edging. The hindwings are fuscous or light fuscous. Adults fly from mid-June to August, and the species produces one generation per year. The larvae live inside a silk web close to the roots of Thymus species.
