Rose Slug Sawfly
A small, dark sawfly whose slug-like larvae skeletonize rose leaves by feeding on the upper leaf surface. Larvae are pale yellowish-green and covered in a thin mucus layer.
Did You Know?
Damaged rose leaves develop a characteristic translucent, papery appearance as only the lower epidermis remains after larval feeding.
Waterlily Leaf Beetle
A small, brown leaf beetle that feeds on the upper surfaces of waterlily pads. It creates distinctive feeding grooves across floating leaves.
Did You Know?
Although it feeds on aquatic plants, the beetle cannot swim and will drown if it falls off a lily pad into open water.
