The species was observed for the first time in the United Arab Emirates in January 2020, in Wadi Wurayah National Park, in the Hajar Mountains within the Emirate of Fujairah: a few Indian fritillaries were found flying with members of a physically similar species, the Plain tiger (Danaus chrysippus). It is thought that they came there as opportunistic migrants because of the suitable conditions created by abundant rainfall in the country since October 2019, and that they would not stay for the summer.
