Dolicharthria punctalis
In 3 days ~10% in a week ~20%
Dolicharthria punctalis, the long-legged china-mark, is a species of moth of the family Crambidae. It is the type species of the proposed genus Stenia, which is usually included in Dolicharthria but may be distinct. It is found mainly in central and southern Europe, but has been recorded further north. The wingspan is 20–25 mm. The moth flies from May to September depending on the location.
The caterpillars feed on Centaurea (knapweeds), Plantago (plantain herb), Trifolium (clovers), Artemisia vulgaris (common wormwood) and even the marine eelgrass Zostera marina. Yet other unusual recorded foods are dry leaves, plant waste, and old roots. Wikipedia →

Rare
Under 5% of wildlife watchers report a Long-Legged China-Mark sighting in Vienna on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 575th most-seen of the 1406 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.
July
In that month about 10% of wildlife watchers report a Long-Legged China-Mark in Vienna on a given day, against under 5% in August to June, the lowest months. That is one of Vienna's wettest months, with about 90 mm of rain against 40 mm in February.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Long-Legged China-Mark sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
2nd of 3
Of the 3 cities where we can rate Long-Legged China-Mark sightings, Vienna ranks 2nd at under 5%. The best odds are in Budapest (Hungary, about 10%).
Same family: Crambidae
The closest relatives of the Long-Legged China-Mark that you can see in Vienna (family Crambidae, Crambid Snout Moths) are Box Tree Moth (about 10%), Straw-Barred Pearl (about 10%) and Rusty Dot Pearl (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Long-Legged China-Mark is recorded against all the insects logged in Vienna (23 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.
