Heliothis viriplaca, the marbled clover, is a moth of the family Noctuoidea. It is found in Europe and across the Palearctic to Central Asia then to Japan, Korea and Sakhalin. In the south, it penetrates to Kashmir and Myanmar. As a migratory moth, it also reaches areas in northern Fennoscandia in some years. North of the Alps, both indigenous and immigrant individuals occur in certain areas. The heat-loving species occurs mainly on dry grasslands, fallow land, heathlands and sunny slopes and slopes and the edges of sand and gravel pits.
The wingspan is 25–30 mm. Meyrick describes it thus- Forewings greyish-ochreous, slightly greenish -tinged, paler before and beyond reniform; first and second lines indistinct; median shade rather dark fuscous, confluent with large dark fuscous reniform; subterminal line rather paler, preceded by a darker or fuscous fascia, darkest at extremities. Hindwings ochreous-whitish, towards base suffused with blackish; a large discal spot, and terminal band including an ochreous-whitish spot blackish. Larva green to purplish-brown; dorsal line darker-edged; subdorsal whitish, dark-edged beneath; spiracular green or yellowish; subspiracular white; head green, pink, or yellowish, brown -speckled.
The moth flies in two to three generations from May to August. [1]. The larvae feed on species from the genera Crepis, Trifolium, Silene, Ononis and Centaurea. Wikipedia →

With luck
About 10% of wildlife watchers report a Marbled Clover sighting in Berlin on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 322nd most-seen of the 1065 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
In that month about 10% of wildlife watchers report a Marbled Clover in Berlin on a given day, against under 5% in August to June, the lowest months. That is one of Berlin's wettest months, with about 80 mm of rain against 30 mm in April.

Across all the parks we cover, that three-hour window holds the most Marbled Clover 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.

GBIF citizen-science records
It is estimated from how often the Marbled Clover is recorded against all the insects logged in Berlin (32 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.
