Australian Satin Sawfly
A large Australian sawfly with a satiny dark blue-black body. Larvae are robust and feed in clusters on eucalyptus foliage.
Did You Know?
The larvae tap their bodies rhythmically against the branch when disturbed, producing vibrations that may alert other larvae in the colony.
Pear Leaf-curling Midge
A minute gall midge whose larvae cause pear leaves to roll tightly inward along their margins. Multiple generations can occur per year, progressively damaging pear tree foliage.
Did You Know?
The larvae manipulate plant growth hormones to force leaves to curl around them, creating a protective shelter.
