Phyllocnistis unipunctella is a moth of the family Gracillariidae. It is known from all of Europe. The wingspan is 7–8 mm. A whitish moth with yellowish suffusion and a distinct black spot near the wing apex. The forewings are shining white, posteriorly more or less ochreous-tinged; often a suffused spot on dorsum near base and a larger one in middle of disc dark fuscous; a transverse dark fuscous line at 2/3, preceded by one and followed by two dark fuscous streaks from costa; a round black apical dot; three dark fuscous diverging bars in apical cilia. Hindwings are light grey. The larva is pale green.
Adults are on wing in July and from September onwards, sometimes overwintering in haystacks. The larvae feed on Populus balsmifera, Populus x canadensis, Populus candicans, Populus deltoides, Populus euphratica, Populus gileadensis, Populus nigra, Populus simonii, Populus suaveolens and Populus trichocarpa. They mine the leaves of their host plant. Wikipedia →

Rare
Under 5% of wildlife watchers report a Poplar Bent-Wing sighting in London on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1300th 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.
September
In that month about 10% of wildlife watchers report a Poplar Bent-Wing in London on a given day, against under 5% in October to August, the lowest months.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Poplar Bent-Wing sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Poplar Bent-Wing is recorded against all the insects logged in London (6 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.
