Eupithecia
genus of insects
Eupithecia is the largest genus of moths of the family Geometridae, and the namesake and type genus of tribe Eupitheciini. Species in the genus are, like those of other genera in the tribe, commonly known as pugs. The genus is highly speciose, with over 1400 species, and members of the genus are present in most of the world with exception of Australasia. Roughly a quarter of described Eupithecia species occur in the Neotropical realm, where they have an especially high species diversity in the montane rain forests of the Andes. The genus includes a few agricultural pest species, such as the currant pug moth, Eupithecia assimilata, which is a pest on hops, and the cloaked pug moth, Eupithecia abietaria, which is a cone pest in spruce seed orchards.
Adult specimens of Eupithecia are typically small, often between 12 and 35 mm, with muted colours, and display a large amount of uniformity between species. As a result, identification of a specimen as part of genus Eupithecia is generally easy, but identifying the exact species is difficult and often reliant on examination of the dissected genitals. Most species share a characteristic resting pose in which the forewings are held flat at a right angle to the body—that is, the costal margins of both forewings form a more-or-less horizontal line—while the hindwings are largely covered by the forewings. They are generally nocturnal.
Of the species where the larval behaviour is known, most feed from the flowers and seeds of their food plants rather than the foliage.
Begin with the source’s own compact description: “Eupithecia” is genus of insects. The dossier treats that line as a proposition to test through Eupithecia, genus and insects, not as a finished interpretation.
Why this record matters
The phrase “genus of insects” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Mar 24, 2026. The linked authority identifier is Q138267. The first chronological checks are 1400.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.

Three-step research path
- Establish the record: confirm the title “Eupithecia”, its source revision and the description used here.
- Expand the search: follow Eupithecia primary sources, Eupithecia archive and Eupithecia research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
