Steel-blue Sawfly larvae are also known as 'spitfires' as they can eject an irritating fluid from their mouth. This defence method ensures predators avoid them, enabling them to reach high numbers.
The Steel-blue Sawfly lives in urban areas, forests and woodlands.
The Steel-blue Sawfly is found in south-eastern Australia.
Feeding and diet
