Esperia sulphurella, also known as the sulphur tubic, is a species of gelechioid moth in the family Oecophoridae. It is native to Europe, but has been introduced in California. Adults have a body length of 6–8 millimetres (0.24–0.31 in), and its wingspan is 12–16 millimetres (0.47–0.63 in). The wingspan is between 12 and 16 millimeters. They have a dark brown ground colour. The forewing has a pale yellow marking. The predominantly pale yellow hind wings are dark brown at the tips. At about two-thirds of the length of the antennae, the antennae have a white band.
They are on wing in spring. The larvae are black and feed on dead wood. Wikipedia →

With luck
About 10% of wildlife watchers report a Sulphur Tubic sighting in London on a given day, based on 166 verified sightings from GBIF citizen-science data. It is the 199th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
April
In that month about 30% of wildlife watchers report a Sulphur Tubic in London on a given day, against under 5% in June to January, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Sulphur Tubic sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 15 cities where we can rate Sulphur Tubic sightings, London has the highest daily chance: about 10%. Next come Birmingham (United Kingdom, about 10%) and Rome (Italy, about 10%).
Same family: Oecophoridae
The closest relatives of the Sulphur Tubic that you can see in London (family Oecophoridae, Concealer Moths) are Ruddy Streak (about 20%), Brown House Moth (about 10%) and White-Shouldered House Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sulphur Tubic is recorded against all the insects logged in London (166 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.
