Halictid Stylops
A twisted-wing parasite that targets sweat bees in the family Halictidae. Parasitized bees show altered behavior and suppressed reproduction.
Did You Know?
Parasitized bees are effectively castrated and their behavior changes so dramatically the phenomenon is called parasitic castration.
Leaf-Rolling Rose Sawfly
A tiny black sawfly that causes rose leaflets to roll downward into tight cylinders. The larva feeds inside the rolled leaf shelter.
Did You Know?
The female injects a chemical into the leaf margin during egg-laying that causes the leaf to roll tightly, creating a protective tube for the developing larva.
