Green-legged Sawfly
An Australian pergid whose larvae feed gregariously on eucalyptus foliage. Heavy defoliation can stress and weaken young plantation trees.
Did You Know?
Larvae regurgitate a pungent eucalyptus-oil-based liquid as a chemical defense against birds.
Dock Sawfly
A small, shiny dark green to black sawfly with pale legs. Larvae are pale green caterpillar-like grubs that feed on dock and sorrel leaves.
Did You Know?
In North America, dock sawfly larvae sometimes bore into apples to pupate, making them a nuisance pest in orchards despite not actually feeding on the fruit.
