Rare
Under 5% of wildlife watchers report an Apple Leafminer sighting in Moscow on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 467th most-seen of the 1111 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Apple Leafminer in Moscow on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Apple Leafminer sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
8th of 8
Of the 8 cities where we can rate Apple Leafminer sightings, Moscow ranks 8th at under 5%. The best odds are in Liverpool (United Kingdom, about 30%), London (United Kingdom, about 10%) and Birmingham (United Kingdom, about 10%).
Same order: Lepidoptera
The closest relatives of the Apple Leafminer that you can see in Moscow (order Lepidoptera, Butterflies and Moths) are Green-Veined White (about 10%), Scarce Tortoiseshell (about 10%) and Common Blue (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Apple Leafminer is recorded against all the insects logged in Moscow (20 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.
