A widespread species but not as common as its sister species T.limniace. Slow gliding flight. Sexes are very similar in appearance. In early morning the males often congregate with some other Danaid species to feed on pyrrolizidine alkaloids oozing from the stems and seed pods of Senna bushes. Multivoltine with several broods per annum.
