Species notes from the sources
Etymology: Specific epithet in honor of Edward Louis Graef (d.1922), one of the founders of the Brooklyn Entomological Society. In his history of the society, Graef joked that a large percentage of moths named for him and his friend J.B. Smith ultimately did not survive. Smith wrote of the new genus and species Graefia smithii , "if anything will kill this genus it is the combination of names." He was half right. Graefia is now a junior synonym of Animomyia but J.B. Smith lives on as Animomyia smithii .
About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Eupithecia graefii. 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.
