Oligocentria semirufescens
species of insect

Oligocentria semirufescens, the red-washed prominent moth or rusty prominent, is a moth of the family Notodontidae. The species was first described by Francis Walker in 1865. It is found in North America from Nova Scotia west to Vancouver Island, south to Florida, Colorado and central California.
Western populations of O. semirufescens are paler and greyer than those from eastern Canada, and superficially resemble the southern Oligocentria perangulata.
The wingspan is 30–45 mm. Adults are on wing from May to September, but from June through early August in Alberta.
The larvae feed on various trees and shrubs, including apple, beech, birch, poplar, oak, maple, rose and willow.

This brief starts where responsible research should: with the source description of “Oligocentria semirufescens” as species of insect. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of insect. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 22, 2026. The linked authority identifier is Q7086813. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1865.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
