Oak Apple Gall Wasp
A gall wasp that creates large spongy apple-like galls on oak twigs. It has an alternating sexual and asexual generation cycle.
Did You Know?
The asexual generation develops in root galls underground, while the sexual generation produces the conspicuous twig galls.
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.
