Anacampsis populella is a moth of the family Gelechiidae, which is native to Europe and has been accidentally introduced to North America. It was first described in 1759 by Carl Alexander Clerck, a Swedish entomologist. The type specimen is from Sweden. The foodplants of the larvae are poplars (Populus species) and willows (Salix species).
The wingspan is 14–19 mm, the colours are variable and the sexes are similar. Abdomen with segments 2-4 often ochreous-yellow. Forewings are whitish, more or less irrorated with black or dark grey, usually palest towards base of costa; costal edge sometimes yellowish-tinged; sometimes a large black patch occupying dorsal 2/3 from base to near tornus stigmata blackish, often concealed; a whitish obtusely angulated fascia at 3/4, indented above angle, sometimes indistinct terminal black dots. Hindwings over 1, rather dark grey. The larva is pale grey-greenish or yellowish; dots black; head and plate of 2 black. A similar species, A. blattariella is also a variable species and can only be told apart from A. populella by genitalia dissection.
They are on wing from June to September, depending on the location, and can be found on tree... Wikipedia →

Rare
Under 5% of wildlife watchers report a Poplar Sober sighting in Saint Petersburg on a given day, based on 67 verified sightings from GBIF citizen-science data. It is the 97th most-seen of the 448 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Poplar Sober in Saint Petersburg on a given day, against under 5% in September to June, the lowest months. Those are among Saint Petersburg's wettest months, with about 100 mm of rain a month against 40 mm in February.
Yes
Of the 2 cities where we can rate Poplar Sober sightings, Saint Petersburg has the highest daily chance: under 5%. Next come Moscow (Russia, under 5%).
GBIF citizen-science records
It is estimated from how often the Poplar Sober is recorded against all the insects logged in Saint Petersburg (67 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.
