Sawfly (general)
Suborder Symphyta
Sawflies belong to the same order as wasps, bees, and ants, but represent a more primitive group. They are not true flies. They are named for the female's saw-like ovipositor, which she uses to cut slits into plants to lay her eggs. The adults are stout-bodied and wasp-like but lack the narrow 'waist'. The most commonly encountered stage is the larva, which looks remarkably like a caterpillar. In Australia, the larvae of pergid sawflies are known as 'spitfires' and are often seen in large, writhing clusters on eucalypt trees. These larvae can cause significant defoliation of their host plants and are considered pests of native trees in gardens and plantations. Adults are harmless and do not sting.
For effective control and prevention, professional pest management is recommended.

Larvae are distinguished from true caterpillars by having six or more pairs of fleshy prolegs on their abdomen (caterpillars have five or fewer) and a single, simple eye on each side of the head.. Specimens are best observed during their peak activity periods and in their preferred microhabitats. Digital photography with macro capabilities can aid in confirming identification markers for consultation with entomological specialists.

Biology & Lifecycle
Understanding Sawfly (general) biology and development
Anatomy
Sawfly (general) (Suborder Symphyta) exhibits typical wasp anatomy with specialized adaptations. Body structure follows standard arthropod organization. Sexual dimorphism may be present between males and females. These anatomical features are optimized for their ecological role and contribute to their success in Australian environments.
Lifecycle Details
Nesting
The female uses her ovipositor to insert eggs into plant tissue, such as leaves or stems.
Lifespan
The larval stage can last for several months before they move down to the soil to pupate.
Larval Stage
The caterpillar-like larvae hatch and feed on the plant's foliage. Many species are gregarious, feeding in large groups. When threatened, 'spitfire' larvae will raise their heads and exude a thick, sticky, eucalyptus-smelling fluid.
