About Tethea ocularis Linnaeus, 1767
Tethea ocularis, commonly known as the figure of eighty, is a moth species belonging to the family Drepanidae. This species was first formally described by Carl Linnaeus in the 12th edition of Systema Naturae, published in 1767. It occurs across all of Continental Europe, and has a scattered distribution in England and Wales. It is not found in Scotland or Ireland. This moth has a wingspan ranging from 35 to 45 mm. Its dark brown forewings feature dark-centred white stigmata that strongly resemble the number 80, giving the species its common name. The hindwings of Tethea ocularis are grey in color. Adults of this species fly between May and July, and they are attracted to both light and sugar. The species' grey and white larvae feed on poplar and aspen. Tethea ocularis overwinters in the pupal stage.
