Pontia edusa
In 3 days ~60% in a week ~90%
Pontia edusa, the eastern Bath white, is a butterfly in the family Pieridae. Pontia edusa is a small to medium-sized migrant butterfly, with a wingspan reaching about 45 mm. The upperside of the wings is white, with black stains on the top of the forewing and hindwing. The hindwing undersides have greenish-grey spots. The butterfly is nearly identical to Pontia daplidice, making the western extent of its range difficult to ascertain. Investigations of the genitals and DNA analysis are the only way to distinguish between these two types.
The adults fly from March to October with two to four generations depending on the latitude. The eggs are laid singly and have an incubation period of seven days. The caterpillars are present from May. They are greyish-greenish, with black dots and broad yellow stripes, quite similar to the larva of the cabbage butterfly (Pieris brassicae). The larvae feed on Resedaceae species. Pontia edusa hibernates in the chrysalis stage.
It is found from the south east of Europe (southern France, Italy, Corsica, Sardinia) up to central Europe and the Middle East in Iran and Iraq. It is a migrant which can also be encountered... Wikipedia →

Possible
About 30% of wildlife watchers report an Eastern Bath White sighting in Ankara on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 12th most-seen of the 32 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
March and October
In those months about 40% of wildlife watchers report an Eastern Bath White in Ankara on a given day, against under 5% in September and November–February, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Eastern Bath White sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 22 cities where we can rate Eastern Bath White sightings, Ankara has the highest daily chance: about 30%. Next come Athens (Greece, about 20%) and Yerevan (Armenia, about 10%).
GBIF citizen-science records
It is estimated from how often the Eastern Bath White is recorded against all the insects logged in Ankara (12 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.
