Colias erate, commonly known as the eastern pale clouded yellow, is a species of butterfly in the family Pieridae. It is found from south-eastern Europe, through Turkey over Central Asia up to Japan and Taiwan. To the south, its range stretches to Somalia and Ethiopia. The species was first described by Eugenius Johann Christoph Esper in 1805.
The butterfly flies in May to September in two generations. The larvae feed on various Fabaceae species, such as Medicago sativa and Medicago, Trifolium, Onobrychis and Melilotus species.

Rare
Under 5% of wildlife watchers report an Eastern Pale Clouded Yellow sighting in Taipei on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 498th most-seen of the 765 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.
June
In that month about 10% of wildlife watchers report an Eastern Pale Clouded Yellow in Taipei on a given day, against under 5% in July to May, the lowest months. That is one of Taipei's wettest months, with about 270 mm of rain against 90 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Eastern Pale Clouded Yellow sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 cities where we can rate Eastern Pale Clouded Yellow sightings, Taipei ranks 2nd at under 5%. The best odds are in Almaty (Kazakhstan, about 10%).
Same family: Pieridae
The closest relatives of the Eastern Pale Clouded Yellow that you can see in Taipei (family Pieridae, Whites, Yellows, and Sulphurs) are Indian Cabbage White (about 20%), Small White (about 10%) and Lemon Migrant (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eastern Pale Clouded Yellow is recorded against all the insects logged in Taipei (13 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.
