Pear Fruit Sawfly
A small, dark sawfly that is a pest of pear orchards. Larvae bore into developing pear fruitlets, causing premature fruit drop.
Did You Know?
Infested young pears often show a distinctive entry hole with wet frass, and a single larva may damage two to three fruits before completing development.
Gum-Tree Pergid Sawfly
A robust Australian sawfly with a dark, polished body. Its gregarious larvae cluster on eucalyptus branches and produce a strong eucalyptus odor when disturbed.
Did You Know?
The powerful eucalyptus-oil smell released by disturbed larvae can be detected from several meters away and serves as a chemical defense.
