The lime leaf miner (Phyllonorycter issikii) is a moth of the family Gracillariidae. It is native to Japan, Korea and eastern Russia, but was probably introduced to eastern Europe around 1970. It is now widespread in the Czech Republic and Slovakia and is expanding its range in Hungary and Germany. It has also been recorded from the Baltic states and also the Benelux in 2009.
The wingspan is 7-7.5 mm. Adults are on wing from the end of June to mid-July and from the end of July to the end of August in two generations. The larvae feed on Tilia americana, Tilia cordata and Tilia platyphyllos. They mine the leaves of their host plant. Wikipedia →

With luck
About 10% of wildlife watchers report a Lime Leafminer sighting in Minsk on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 91st most-seen of the 196 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
October
In that month about 20% of wildlife watchers report a Lime Leafminer in Minsk on a given day, against under 5% in July and November–May, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Lime Leafminer sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Of the 8 cities where we can rate Lime Leafminer sightings, Minsk has the highest daily chance: about 10%. Next come Moscow (Russia, under 5%) and Helsinki (Finland, under 5%).
GBIF citizen-science records
It is estimated from how often the Lime Leafminer is recorded against all the insects logged in Minsk (10 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.
