The larvae of the Swordgrass Brown Butterfly feed almost exclusively on Gahnia sedges. In their semi to open habitat, they can be observed flying from November to February. The Swordgrass Brown Butterfly seems to rest with its wings open rather than shut, far more frequently than other butterflies.
The species is not seen as much as it once was due to the drainage, fragmentation and degradation of its sedge wetland habitats due to urbanization but sometimes can be locally common.
The adult butterflies have broad yellow diagonal strip across each forewing with two eyespots, one small and one large. The hind wings have one eye spot each.
In Baw Baw Shire you may catch sight of one of these butterflies anywhere sedges grow: Golden Whistler, Bellbird Park, Robin Hood, Thornells, John Lardner Reserve.
