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.

Belkin's Dune Tabanid Fly

A rare horse fly known only from the El Segundo sand dunes in Los Angeles County. Larvae develop in the sand and adults are seldom encountered.

💡

Did You Know?

Most of the El Segundo dunes were destroyed to build Los Angeles International Airport.
