Giant Robber Fly
A large, bristly predatory fly with powerful grasping legs and a sharp proboscis. It ambushes prey in mid-air with remarkable speed and precision, including insects larger than itself.
Did You Know?
Robber flies inject prey with saliva containing neurotoxins and digestive enzymes, liquefying the insides and then sucking them out.
Spittlebug
A small, stout brown bug whose nymphs produce masses of frothy white "spittle" on plant stems. The foam protects them from predators, parasites, and desiccation.
Did You Know?
Spittlebug nymphs produce their protective foam by blowing air through a secretion from their abdomen, creating a humid microenvironment that shields them from the sun.
