Colourful green-yellow-orange sawfly larvae with black heads 25mm
On Melaleuca quinquenervia.
These sawfly totally destroy my young paperbarks each year. When the larvae are very small they only eat the soft parts of the leaf leaving a skeleton of veins. See here... www.projectnoah.org/spottings/9364491 ref... http://australianmuseum.net.au/Sawflies
