Giant Swamp Leaf Beetle
One of the larger species of reed beetle, with a metallic golden-green to coppery body and distinctive long antennae. Adults rest on emergent aquatic plants in wetlands.
Did You Know?
Like all Donaciinae, larvae breathe underwater by piercing plant roots and tapping into the air spaces (aerenchyma) inside the plant tissue.
Pepe Tuna (Bag Moth)
A native New Zealand bag moth whose caterpillars construct elaborate portable cases covered with twigs and leaf fragments. Female adults are wingless grubs that never leave their bags. Males are small dark moths that fly to find stationary females.
