Two-spotted Eugnosta - Hodges#3763
Eugnosta bimaculana
This record describes Eugnosta bimaculana (species). Recorded family: Tortricidae. Recorded order: Lepidoptera.
Identification and Appearance
Adult - forewing light brown with two large dark brown patches in median and subterminal areas; median patch does not reach inner margin creating two separate patches when wings held together at rest. Eugnosta bimaculana was originally assigned #3783 in the 1983 Hodges Checklist. At that time, most of the species in Cochylini (then considered to be Cochylidae) were not assigned to genera. Today, they are placed mostly in a variety of genera which, if the old numbering system is retained, would result in a list of confusing appearance.

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