Affected leaves have a brown "blistered" appearance (Fig. Sawflies first appeared 250 million years ago in the Triassic. Sawflies are also found on Paperbarks (Melaleuca). The larvae of the Steel-Blue Sawfly pupate in a cocoon in the leaf litter, while Bottlebrush Sawflies pupate without a cocoon. Sawfly Larvae Hivemind. Larvae do not have the abdominal prolegs. Rain can be a significant cause of mortality - the thin covering of the mines is easily perforated and water enters, drowning the larvae. Still, any help to revive my Mugos would be very much appreciated. Some Sawfly larvae are commonly called Spitfire Grubs. In the female the top and sides of the prothorax and usually the last two segments of the abdomen are orange, and there is no black around the simple eyes. Repeat applications would be needed to counter reinfestation. Another notable difference, though it requires a closer look, is that caterpillars have tiny hooks called crochets, on the ends of their prolegs.

The current economic effect of this insect is unknown, but is likely to be minimal due to the success of the introduced biological control agent Bracon phylacteophagus Austin. The Bottlebrush Sawfly is another species of Pterygophorus, P. cinctus, which feeds on Bottlebrush (Callistemon). Sawflies do not possess the distinctive thin waist of the other hymenopterans, nor do they possess a sting. When disturbed, larvae tap their abdomens up and down and regurgitate the Eucalyptusoil as thick yellow fluid. Sawflies belong to the Sub-order Symphyta in the Order Hymenoptera.

At this time it was found only within a 7-km radius of Auckland International Airport. They pupate in soil and litter. Sawfly larvae feed mainly on native trees and shrubs, such as eucalypts, paperbarks and bottlebrushes, although a small number of species are parasitic.

Distribution to new localities may also occur through such means as the transfer of infested plants from nurseries, and the inadvertent transport of infested leaves caught up on motor vehicles. You have reached the end of the main content. The female sawfly uses this ovipositor to saw a slit in plant leaves and stems, into which she then lays her eggs.
