The Eastern Pale Clouded Yellow is a very mobile species and can therefore be seen in all sorts of places. This species greatly extended its range during the 1970s and 80s. 50 years ago this mainly Asian species was known in Europe only from the Black Sea coast. Lucerne (Medicago sativa) is its most important larval foodplant and they are most numerous in areas where it is grown. The caterpillars can also be found on other leguminous plants. This species has several generations a year; three to five have been reported from Bulgaria and Romania. This species passes the winter as a caterpillar (probably without diapause).
