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.
Mottled Tortoise Beetle
A small tortoise beetle with variable coloration, often gold with irregular black spots on the elytra. Like its relatives, it has broadly expanded margins that overhang the body.
Did You Know?
Its coloring can shift between gold and dull orange-brown depending on humidity and the beetle's physiological state.
