Pergidae

Spitfire Perga affinis larvae, copyright Gordon Smith.

Belongs within: Tenthredinoidea.

The Pergidae are a group of sawflies most diverse in Australia and South America with fewer species in North America and Asia. They are divided between numerous subfamilies with the largest species belonging to the Australasian Perginae. Larvae of this subfamily are often notable defoliators of Eucalyptus. Perginae and Philomastix have the mesoscutellum lobed or produced posteriorly (Naumann 1991). The Euryinae and Styracotechys possess a petiolate anal cell in the fore wing (Naumann 1991).

Characters (from Naumann 1991): Adult 2.8-30 mm; antennae 5-24-segmented; head sometimes with complete hypostomal bridge; neck short; fore wing without crossvein 2r, fore tibia with one or two apical spurs. Larva with 3-5-segmented legs with claws; abdominal prolegs on segments 2-6, 2-8 or 3-8 and 10, sometimes only on 10 or completely absent; stemmata present; antennae variable from disc-like to multisegmented.
