Euthalia anosia is quite widely distributed and can be common locally. This species is sexually dimorphic with differences in both colour and markings. The base colour of the wings can be blue, greyish-brown, or a combination of the two in both male and female. The female is also considerably larger than the male. Like most species in this genus it is a strong flier and easily disturbed. It is multivoltine with several broods per annum. Further study is needed for this species.
