Cauchas rufimitrella
In 3 days ~10%
Cauchas rufimitrella is a diurnal lepidopteran from the family Adelidae, the fairy long horn moths. It is found in almost all of Europe, except Portugal, Ukraine and the southern part of the Balkan Peninsula. The wingspan of the moth ranges from 10 to 12 millimeters. The thick erect hairs on the head vertex are black, more or less ferruginous-mixed above. Antennae in male 2 [2x the length of the wing], in female 1.5, black, tip whitish. The forewings are shining brassy bronze, sometimes partly or wholly coppery or metallic red purple. The hindwings are dark purplish fuscous.
The flight time is May to June. Caterpillars live on the seeds of Cardamine pratensis and then they pupate over the winter. Wikipedia →

Rare
Under 5% of wildlife watchers report a Meadow Longhorn sighting in Moscow on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 992nd most-seen of the 1111 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Meadow Longhorn in Moscow on a given day, so our monthly data shows no clear season.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Meadow Longhorn 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 7 cities where we can rate Meadow Longhorn sightings, Moscow ranks 7th at under 5%, level with the leaders once rounded. The best odds are in Munich (Germany, under 5%), Paris (France, under 5%) and Birmingham (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Meadow Longhorn is recorded against all the insects logged in Moscow (5 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.
