Slender Robber Fly

A delicate, narrow-bodied robber fly with an extremely slender abdomen. It hunts small insects among tall grass stems.

💡

Did You Know?

Its thread-like abdomen makes it almost invisible when resting on grass stems.

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.
