Patania ruralis, the mother of pearl moth, is a species of moth in the grass moth family Crambidae. It was described by Giovanni Antonio Scopoli in 1763. Its common name refers to its almost transparent wings which in oblique lighting show a pale blue pearlescent sheen. This is found in Europe, occurring almost across the continent and the nearshore islands, except for those in the Aegean and Western Mediterranean as well as Cyprus. The adults are on the wing from June to September depending on the location. The caterpillars eat mainly Urtica nettles; occasionally they are found on other eudicots.
The wingspan is 26–40 millimetres (1.0–1.6 in). The forewings are pale whitish-ochreous, yellowish-tinged; a grey subcostal suffusion and connected orbicular dot; lines rather dark grey, first straight, second serrate, curved, strongly broken inwards beneath middle; a dark grey discal mark, nearly followed by a grey blotch; a grey terminal band, edge parallel to second line. Hindwings with colour, discal mark, and posterior markings as in forewings. The caterpillar larva is whitish green, sides greener; dorsal line darker; head green.

Rare
Under 5% of wildlife watchers report a Mother Of Pearl 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.
July and August
In those months about 10% of wildlife watchers report a Mother Of Pearl in Munich on a given day, against under 5% in September to June, the lowest months. Those are among Munich's wettest months, with about 140 mm of rain a month against 60 mm in February.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Mother Of Pearl sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
20th of 27
Of the 27 cities where we can rate Mother Of Pearl sightings, Munich ranks 20th at under 5%. The best odds are in Liverpool (United Kingdom, about 30%), Birmingham (United Kingdom, about 10%) and Kyiv (Ukraine, about 10%).
Same family: Crambidae
The closest relatives of the Mother Of Pearl that you can see in Munich (family Crambidae, Crambid Snout Moths) are Box Tree Moth (about 10%), Mint Moth (about 10%) and Garden Grass-Veneer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mother Of Pearl 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.
