Callistemon/Bottlebrush Sawfly ( Pterygophorus species).
Image of an adult sawfly taken in the riparian zone near Sportsman creek. This sawfly does not have the distinctive thin waist of wasps and is incapable of stinging. They pupate in a naked pupa without any covering or cocoon in leaf litter. Their larvae are known as “spitfires” although they do not spit liquid.
