Elaphria trolia - Hodges#9682.2
Elaphria trolia
This record describes Elaphria trolia (species). Recorded family: Noctuidae. Recorded order: Lepidoptera.
Identification and Appearance
Elaphria trolia (Dyar, 1914), stat. n., was described and previously treated as a Central American subspecies of Elaphria exesa (Guenée, 1852), but differs from it in barcodes (3.5%) and male genital characters. So, it is revised to the status of valid species. [Contributed by Jim Troubridge]

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