Idia occidentalis
species of insect

Idia occidentalis is a species of litter moth of the family Erebidae first described by Smith in 1884. It is found in North America from southern Alberta and British Columbia, south to Colorado, Arizona and California.
It was formerly considered a subspecies of Idia lubricalis.
The wingspan is about 30 mm. Adults are on wing in August in the north.
The insect has a yellow-brown colour, and a "cloudy" pattern. It is said the insect's flight history is from May to October, and that it seems to occupy: dry open areas, arid native grasslands, and badlands.

Why this record matters
“Idia occidentalis” is worth following because a concise public description often conceals a longer documentary argument. Here, Idia, occidentalis and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Dec 18, 2022. The linked authority identifier is Q5988691. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1884.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
