Marasmia cochrusalis
This record describes Marasmia cochrusalis (species). Recorded family: Crambidae. Recorded order: Lepidoptera.
Identification and Appearance
FW middle portion of st. line or shade is narrowly separated from the pm. line. The HW pm. and st. lines tend to be more narrowly separated than in trapezalis with pm. line bending more toward the apex. The HW pm. line tends to align with the FW st. line in cochrusalis and with the pm. line in trapezalis . Type locality: Dominican Republic, St. Domingo

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