Wright (2011) reported the forewing length. (2)
♂ 8.1–11.0 mm (mean = 9.2, n = 32), AR = 2.88
♀ 8.2–10.3 (mean = 9.1, n = 21), AR = 2.75
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
Northeastern United States and southeastern Canada. (3)
Beadle & Leckie (2012) included the species on the checklist. (4)
fields and waste places where goldenrod grows; adults are nocturnal and come to light
adults fly from July to September
larvae feed in rootstalks of goldenrod (Solidago spp.)
Misspelling of the specific epithet as "similiana" may have resulted from confusion with the Palearctic species Eucosma similiana (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.
