In 3 days ~10% in a week ~30%
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 Munich on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 254th most-seen of the 521 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April and May
In those months about 10% of wildlife watchers report a Meadow Longhorn in Munich on a given day, against under 5% in June to March, the lowest months.
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.
Yes
Of the 7 cities where we can rate Meadow Longhorn sightings, Munich has the highest daily chance: under 5%. Next come 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 Munich (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.
