Aseptis binotata
species of insect
Aseptis binotata, the rusty shoulder knot moth, is a moth of the family Noctuidae. The species was first described by Francis Walker in 1865. It is found widespread in western North America, west of south-central Alberta, Wyoming, and Nebraska. Along the Pacific Coast it occurs from northern Mexico to south-central British Columbia. It can be found from sea level to altitudes over 2000 meters in a variety of habitats from dense forest to shrub desert.
The wingspan is 29.5–35 mm. It is the most variable species in the genus Aseptis with respect to forewing color and pattern strength. It may be brownish, warm dark brown, pale to medium gray brown, yellowish light brown, or reddish brown depending on locality. The most noticeable marking in dark specimens is the large pale yellowish postreniform patch, which is bisected by the dark postmedial line. The antemedial line is strongly convex laterally and is filled with light tan.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Aseptis binotata”, the useful work is to connect “species of insect” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Apr 7, 2026. The linked authority identifier is Q4804183. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1865 and 2000.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
