Blue Orchard Bee
A metallic dark blue solitary bee that nests in pre-existing holes in wood. It is an exceptionally efficient pollinator of fruit trees, significantly outperforming honey bees per individual.
Did You Know?
A single blue orchard bee can pollinate as effectively as 60 to 80 honey bees, making them increasingly important for commercial fruit production.
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.
