Euxoa satis
This record describes Euxoa satis (species). Recorded family: Noctuidae. Recorded order: Lepidoptera.
Identification and Appearance

Forewing is dark brown to black, hindwing is dark brown/gray. A form with a lighter ground color occurs in Washington, Oregon, and California with paler shading adjacent to the transverse lines on the forewing and pale shading in the reniform and orbicular spots between the black line and the dark central area. Many Euxoa species are difficult to identify and there is often considerable variation in color within species depending on location. Can be confused with other Euxoa species such as E. infausta and E. tessellata.

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