Identification and Appearance

Eucosma dorsiatomana - Hodges#2972 - Eucosma dorsiatomana
Contributed by Robert Lord Zimlich; Additional contributions by Randy Hardy

Adult : FW shades of pale olive-brown or fawn, with a white divided median stripe, ocellic spot, sub-apical costa markings, and inner two-fifths of costa narrowly edged with white. Brown shades are palest along the dorsum, between median streak and costa. White median streak extends from base to end of cell and is evenly divided its whole length by a narrow black line, a heavier black line outlines the white streak below, and a less well defined one above. The inner half of costa is minutely dotted with brown. The dorsal margin from inner fourth to anal angle is distinctly marked with seven or eight equally spaced black dots. HW dark smoky-brown, cilia gray, with a darker basal line. Legs whitish, tarsi shaded with brown. (for detailed description, see reference document)

About Butterflies and Moths: the wider group

Order-level background for Lepidoptera, the group containing Eucosma dorsiatomana. 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.
