Polydrusus Weevil
A small weevil covered in brilliant green scales that sparkle in sunlight. It is commonly found on birch and hazel trees.
Did You Know?
The green coloring comes from tiny iridescent scales that rub off easily leaving the beetle looking dull brown underneath.
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.
