Identification and Appearance

Wingspan 38 to 43 mm. Characterised by its four cross-lines or 'lutestrings' on the inner part of the forewing, this species sometimes shows a slight purplish tinge when fresh. Good photographs and/or the specimen required. June and July is the typical flight time for this moth. The caterpillar feeds on Poplar species, especially Aspen, hiding between two joined leaves. There are three races recognised, occurring in England and Wales, Scotland and Ireland. In a recent survey to determine the status of all macro moths in Britain this species was classified as local. In the most recent VC55 Macro Moth Checklist this species was classed as generally rare, in rapid decline, or species with high mis-ID potential. Good photos and /or specimen will be required.

About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Tethea or. Species-specific details appear above.
Group overview
Lepidoptera includes approximately 180,000 described species of butterflies and moths. Moths outnumber butterflies roughly 10:1. The monarch butterfly's eastern population has declined by more than 80% since the mid-1990s, and the western population by over 95% since the 1980s. The IUCN lists the migratory monarch as Vulnerable.
Ecological role of the group
Butterflies and moths are essential indicators of ecosystem health. As caterpillars, they are a primary food source for birds - a single nest of blue tit chicks requires ~10,000 caterpillars. Adult moths pollinate many night-blooming plants.
Economic and practical significance of the group
Lepidoptera are critical pollinators. In Europe, grassland butterfly species have declined by almost 50% since the early 1990s. In the UK, three-quarters of butterflies are in decline. In the U.S., five butterfly species have gone extinct since 1950, with 29 listed as endangered.
Recorded sources for this group: IUCN Red List, Xerces Society, USFWS, PNAS, WWF. Imported estimates may describe particular regions or reporting periods.
