Identification and Appearance

Pelochrista similiana - Hodges#3116.1 - Pelochrista similiana
Contributed by Robin McLeod; Additional contributions by cotinis , Steve Nanz , Tony-2 , Maury Heiman , Randy Hardy , Blocky

Adult: forewing brown with dark brown L-shaped marking with curved edges, beginning at inner margin in AM area and becoming paler toward center of wing; large faint tooth (sometimes broken) in subterminal area pointing toward anal angle; hindwing dirty white, shading to pale brown toward outer margin Misspelling of the specific epithet as similana may have resulted from confusion with the Palearctic species Eucosma similana (Schiff.), which is now considered a synonym of Epinotia trigonella (Linnaeus 1758), according to these two United Kingdom websites ( 1 , 2 ). The Palearctic Epinotia trigonella (= Eucosma similana ) [ photo 1 , photo 2 ] is obviously a different species than the Nearctic Eucosma similiana As of 2015, the page at BOLD for similiana is composed of two BIN clusters. One of them here is all similiana . The other here has both similiana and dorsisignatana . The specimens identified as dorsisignatana may be misidentified as they are poorly marked. However, the nearest BIN here is composed of only dorsisignatana . The BOLD page for dorsisignatana is also composed of two BIN clusters, the one previously mentioned and another here which mostly contains example which look like the recently described oraria .

About Butterflies and Moths: the wider group

Order-level background for Lepidoptera, the group containing Pelochrista similiana. 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.
