Larch pug
species of insect
The larch pug (Eupithecia lariciata) is a moth of the family Geometridae. The species can be found in Europe, the Ural Mountains, West and Central Siberia, the Altai Mountains, Transbaikalia, Yakutia, the Far East, Mongolia, Korea, Japan and in North America, from Yukon and Newfoundland to New York and Arizona.
The wingspan is 19–22 mm. The length of the forewings is 10–12 mm. The ground colour of the forewings is whitish grey with dark crosslines. The median crossline is sharply angulated. There is a series of small dark stains on the costal margin and tuft of white hairs on the thorax. The hindwings are whitish grey with a small dark spot in the tornal area.
The larva can be quite variable - brown or green, with or without light longitudinal stripes, with or without a number of bell-shaped dark spots along the back.
Similar species
This species is very like Eupithecia castigata, but the fore wings are rather longer, the ground colour is whiter, and the dark-grey or blackish cross lines are rather more angled and slanting; the hind wings are paler, and especially so on the front margins.
This brief starts where responsible research should: with the source description of “Larch pug” 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 Sep 7, 2026. The linked authority identifier is Q1811842. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
