Chocolate-tip

The Chocolate-tip (Clostera curtula) is a moth in the family Notodontidae (prominent moths), distributed widely across the temperate Palaearctic region from western Europe through central Asia. Adult moths are medium-sized with a characteristic chocolate-brown or reddish-brown distal area on the forewings that contrasts with the pale basal area — a pattern from which the common name is derived. The wings are held in a tent-like roof over the body at rest, which, combined with the hairy thorax, creates a convincing bark-like camouflage that provides protection from visually hunting predators during daylight hours. The larvae feed on the leaves of various willows (Salix), poplars (Populus), and aspens — trees common in riparian and lowland habitats throughout the species' range. Like other notodontids, larvae may be gregarious in early instars, feeding together before dispersing for later instars. The species produces two or more generations per year in warmer parts of its range, overwintering as a pupa in a cocoon on or in the ground. The IUCN classifies the Chocolate-tip as Least Concern; it is a moderately common and widespread species across Europe and Asia wherever suitable Salix and Populus host trees occur. It is attracted to light traps and is regularly recorded in moth surveys.
