Slender pug
species of insect
The slender pug (Eupithecia tenuiata) is a moth of the family Geometridae. It was first described by Jacob Hübner in 1813 and is found throughout Europe and western parts of the Palearctic. The larva feeds on the catkins of willow (Salix species).
Life cycle and description
A single brooded species, this is one of the smallest of the geometrids, with a wingspan of only 14–16 mm. The forewing ground colour is light greyish ochreous. There are numerous curved dark fuscous striae, the veins and costa are ochreous brown. The edges of the biangulate median band form dark costal spots. The forewing has a dark ovoid discal mark. The forewings lack a tornal spot and the hindwings are whitish grey with dark striae, and a small discal spot.
It flies at night in June and July and is attracted to light and can be found by day at rest on the trunks of large sallows.

Why this record matters
“Slender pug” is worth following because a concise public description often conceals a longer documentary argument. Here, Slender, species and insect 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 Jun 2, 2025. The linked authority identifier is Q1811826. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1813.
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.
