The Chevron

Eulithis testata

This record describes Eulithis testata (species). Recorded family: Geometridae. Recorded order: Lepidoptera.

Identification and Appearance

The Chevron - Eulithis testata

Wingspan 25 to 35 mm. Quite a variable species, this moth displays colour forms from yellowish through to fairly dark brown. It inhabits moorland habitats as well as sandy and woodland areas. The adults fly in July and August in a single generation. The larval foodplants are Willow, Aspen and Birch. Widespread and fairly frequent in Britain. In a recent survey to determine the status of all macro moths in Britain this species was classified as common. This species has declined in our area with few recent records. No additional images available for this species.

About Butterflies and Moths: the wider group

Order-level background for Lepidoptera, the group containing Eulithis testata. 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.
