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.
Forest Tent Caterpillar Moth
A widespread North American moth whose caterpillars defoliate vast areas of hardwood forest. Despite the name, they form silken mats rather than true tents.
Did You Know?
Outbreaks can defoliate millions of hectares of forest, though healthy trees usually recover with new leaves.
