Insect
Northern Sword-grass Brown
Tisiphone helenaAlso known as Helena Brown
Northern sword-grass browns glide low along shaded edges and sunlit clearings within the upland rainforests of northeastern Queensland. Caterpillars feed nocturnally on razor-sharp sword-grasses, hiding deep inside dense tussocks during daylight to evade woodland predators. Adults patrol forest pathways with a bouncing flight pattern, pausing frequently on broad leaves to bask with wings partially open.
