Rice Water Weevil
A small, grey-brown weevil that feeds on rice roots as a larva and on rice leaves as an adult. Adults create distinctive narrow feeding scars along the surface of rice leaves parallel to the leaf veins.
Did You Know?
Larvae feed underwater on rice roots, surviving by obtaining oxygen from the rice plant's aerenchyma tissue through specialized spiracles.
Children's Stick Insect
A large Australian leaf insect with broad flattened body and legs. Females are vivid green and resemble eucalyptus leaves. Males are more slender and brown. It was named after the curator of the British Museum.
