In 3 days ~10% in a week ~30%
Euchloe ausonia, the eastern dappled white, is a southern European and Palearctic butterfly found mostly to the south and east of its almost indistinguishable relative the western dappled white. The wingspan is 36–48 mm. The forewings are white with black tips and a black spot. The underside is characterized by black and yellow scales, which create a greenish-white pattern. The female is generally darker. The two generations differ in pattern. The colour of the caterpillar varies from yellowish to greenish to bluish. It has obvious side stripes. The dorsal line and the dorsal side line are darker than the base colour. The segments have numerous, very small, black dots. The pupa is light brown and relatively slim.
Euchloe ausonia occurs in Europe in central and southern Italy as well as in the Balkan Peninsula including most of the larger, Greek islands. The northern border in Europe runs through southern Austria, Hungary and southern Ukraine. In the east, the presence in the south continues to Israel and Jordan and in the east to northern Iraq, Iran and Afghanistan, to the north via the Caucasus up to southern Kazakhstan and across...

Rare
Under 5% of wildlife watchers report an Eastern Dappled White sighting in Istanbul on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 234th most-seen of the 266 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.
March to May
In those months about 10% of wildlife watchers report an Eastern Dappled White in Istanbul on a given day, against under 5% in June to February, the lowest months.
3rd of 3
Of the 3 cities where we can rate Eastern Dappled White sightings, Istanbul ranks 3rd at under 5%. The best odds are in Jerusalem (Israel, about 10%) and Rome (Italy, about 10%).
Same family: Pieridae
The closest relatives of the Eastern Dappled White that you can see in Istanbul (family Pieridae, Whites, Yellows, and Sulphurs) are Small White (about 20%), Clouded Yellow (about 10%) and Large White (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eastern Dappled White is recorded against all the insects logged in Istanbul (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.
