Distribution Australia, from Tasmania to Kuranda in north Queensland and west to Mount Gambier in South Australia. Species lie within the 30 inch annual unifrom rainfall belt. There is a geographic disjunction between species ranging to the south of the McPhearson-McLeay overlap and four species in northern Queensland (Tindale, 1933).
Systematics Monophyly not corroborated.
Biology Larvae are grass feeders and at least two species are major farm pests on grazing land or urban lawns, and turf (Ford & Nickson, 2004; McQuillan et al., 2007). An unknown speices has been reported feeding on sugar cane setts in Queensland (Sallam et al., 2011). Oncopera alpina feeds on several species of Poa and may be threatened by future climate warming (Parida et al., 2015)
