The marbled minor (Oligia strigilis) is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is distributed throughout Europe, east through the Palearctic to central Asia and the Altai Mountains. It rises to heights of over 1500 meters in the Alps.
This is a rather small species (wingspan 24–29 mm), the forewings usually being dark brown with a pale subterminal band, the hindwings pale brown. Melanic forms are often encountered, especially in industrial areas. Its wingspan is 24–29 mm. Forewing brownish grey, reddish grey, reddish brown, or blackish; the space between outer and submarginal lines often white or grey, or luteous (muddy yellow), rufous or concolorous with ground colour; the three stigmata ringed with black, either paler than the ground or lost in the dark suffusion; inner and outer lines blackish, conversely edged with paler and dentatelunulate, the pale edging of outer line generally more conspicuous, whitish, below the middle; terminal area dark, forming two blotches one on each fold; a dark costal blotch before submarginal line; a slight black dash...

Rare
Under 5% of wildlife watchers report a Marbled Minor sighting in Vienna on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 1090th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Marbled Minor in Vienna on a given day, so our monthly data shows no clear season.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Marbled Minor sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 3 cities where we can rate Marbled Minor sightings, Vienna ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in London (United Kingdom, under 5%).
Same family: Noctuidae
The closest relatives of the Marbled Minor that you can see in Vienna (family Noctuidae, Cutworm Moths and Allies) are Silver Υ (about 20%), Large Yellow Underwing (about 10%) and Cotton Bollworm Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Marbled Minor is recorded against all the insects logged in Vienna (8 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.
