Yellow-tail
Euproctis similis
This record describes Euproctis similis (species). Recorded family: Erebidae. Recorded order: Lepidoptera.
Identification and Appearance

Wingspan 28-35 mm. The female is larger than the male and has a large tuft of yellow hairs at the tip of her abdomen, which is used to cover the newly-laid eggs. Occupies a number of habitats such as woodland, scrub and gardens. The caterpillars, in common with many of the Lymantriidae , are covered with irritating hairs and should only be handled with extreme care. They feed on a number of deciduous trees and shrubs. Common in England and increasingly so in Scotland. In a recent survey to determine the status of all macro moths in Britain this species was classified as common.

About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Euproctis similis. 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.
