Yoma sabina are found in the northern Australasian realm and in Southeast Asia.
   They can be viewed throughout the year in tropical rainforest lowlands throughout the Northern Territory, Far North Queensland, Papua New Guinea, and Indonesia.
   Their preferred terrain is vine thickets near creeks or moist areas.
   They are a large but elusive species that is quite timid and very easily disturbed.
   Although easily spotted when flying, they descend very quickly and often settle on the underside of leaves, thereby disappearing from sight.
   They fly through most of the year and have several broods per year. 
   Adults are brown with broad orange stripes extending over both wings.
   The ventral sides have a similar pattern but in light and dark brown.
   They mimic other toxic butterflies using their broad yellow orange stripe that extends across both upper and lower wings.
   Their coloring is generally from a medium to a very dark brown, with the ventral side of the wings being a lighter shade.
   The female has a white mark in the black tip of each forewing, a wingspan of 7 cm, and is slightly larger than the male.
   The male has a yellow mark in the same forewing. 
   Although non toxic, they protect themselves from predation by mimicking other poisonous species. (Batesian mimicry)
   Adults have life spans of up to 9 weeks.
