The shark (Cucullia umbratica) is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. This species is widespread throughout much of the Palearctic realm (Europe, Russia, Afghanistan, Turkestan, and Mongolia), but has recently also been reported from North America, from the Magdalen Islands in Canada.
These moths inhabit a range of open environments such as heaths, meadows, forest edges, gardens, parks and suburban areas. Cucullia umbratica is a fairly large species, with a wingspan of 52–59 millimetres (2.0–2.3 in). These moths have long, narrow wings giving a streamlined appearance. The forewings are dull brownish grey, the cell and space beyond are paler, with dull greyish buff. A fine black line runs from the base below cell. The usual lines and stigmata are ill defined. Orbicular is represented by two or three dark points, reniform by a curved black line at lower end. Slight black dashes are present before termen, above vein 3 and below vein 2, and a longer black streak appears above middle of vein 4. The hindwings of male are white, with... Wikipedia →

Rare
Under 5% of wildlife watchers report a Shark Moth sighting in Vienna on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1286th 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 Shark Moth in Vienna on a given day, so our monthly data shows no clear season.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Shark Moth sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 3 cities where we can rate Shark Moth sightings, Vienna ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Helsinki (Finland, under 5%) and Moscow (Russia, under 5%).
GBIF citizen-science records
It is estimated from how often the Shark Moth is recorded against all the insects logged in Vienna (5 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.
