Habitat and Range
Geographic Range
"It is known from the United States, where it is found from coastal South Carolina to south-western Texas." Type locality : Southwest Texas [BMNH].
Seasonal Activity
Adults fly March/April through October . Probably multivoltine in the south and univoltine in the north.
Diet and Behavior
Diet: The larvae feed on Phragmites australis . They mine the leaves of their host plant. The mine has the form of a gallery ranging in length from three to seven cm. The frass is piled at basal end of the mine and expelled from an opening at that end. The larva moves along the mine when disturbed. It hibernates in its cocoon inside the mine.
About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Cosmopterix nitens. 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.
