The Steel-blue Sawfly lives in urban areas, forests and woodlands. The Steel-blue Sawfly is found in south-eastern Australia. Steel-blue Sawfly larvae in the Sydney area feed on eucalypts. The Steel-blue Sawfly can sometimes cause extensive damage to trees.

One very destructive genus is the Steel-Blue Sawfly (Perga sp.) which attacks eucalypts in south-eastern Australia. These larvae secrete an irritating or distasteful liquid from their mouths.
