In 3 days ~10% in a week ~20%
Eupithecia simpliciata, the plain pug, is a moth of the family Geometridae. It is found in the Palearctic realm, from western Europe to north-western China (Xinjiang). The species primarily colonizes wastelands, rubble and abandoned vineyards, and in Asia also salt steppes. In the Alps, the range of altitude extends up to 1200 metres.
The wingspan is 21–23 mm. Eupithecia simpliciata has a relatively broad rounded forewing. The forewing ground colour is pale ochre. The forewing has indistinct, curved fuscous striae. The postmedian fascia has curved pale edges, the outer one zig-zagged towards the tornus. The forewing fringes are chequered. The hindwings are whitish-grey, darkened in the postmedian field. The discal spot is small. The moths vary significantly in colour and pattern.
See also Prout The caterpillars are greenish or brownish coloured and usually show indistinct dark angular or diamond markings on the back. The pupa is brownish, the wing sheaths shimmer greenish. The cone-shaped cremaster is equipped with two curved thorns as well as some short hook bristles.
The moth flies from May to September, depending on the location. The larvae feed on Atriplex, Chenopodium, Artemisia maritima and Artemisia vulgaris. Wikipedia →

Rare
Under 5% of wildlife watchers report a Plain Pug sighting in London on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1394th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Plain Pug in London on a given day, so our monthly data shows no clear season.
Yes
Of the 2 cities where we can rate Plain Pug sightings, London has the highest daily chance: under 5%. Next come Moscow (Russia, under 5%).
Same genus: Eupithecia
The closest relatives of the Plain Pug that you can see in London (genus Eupithecia, Pug Moths) are Lime-Speck Pug (about 10%), Cypress Pug (about 10%) and Common Pug (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Plain Pug is recorded against all the insects logged in London (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
