Field Notes
Description:
"The bright, conspicuous colors of the Giant Mesquite Bug nymphs are a form of aposematic coloration meant to warn potential predators that they are not good to eat. If bothered, the flightless nymphs will produce a stinky secretion to repel predators not already warned off by their bright colors. I have never observed birds bothering Giant Mesquite Bug nymphs, and my dogs avoid any that fall on the ground."
