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 Istanbul on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 156th most-seen of the 266 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
March
In that month about 20% of wildlife watchers report a Sulphur Tubic in Istanbul on a given day, against under 5% in May 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.
Among the best
Of the 15 cities where we can rate Sulphur Tubic sightings, Istanbul ranks 4th at about 10%, level with the leaders once rounded. The best odds are in London (United Kingdom, about 10%), Birmingham (United Kingdom, about 10%) and Rome (Italy, about 10%).
Same order: Lepidoptera

GBIF citizen-science records
It is estimated from how often the Sulphur Tubic is recorded against all the insects logged in Istanbul (11 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.
