Here's the Gulf Frit. caterpillar defoliating a passion vine. The adult Gulf Frit. flew into the picture as I released the shutter. Sorry the adult is blurry, it was moving too fast for the shutterspeed I was using. What's neat about these insects (besides their great orange color) is the fact that they incorporate toxins from the passion flower vine so that they are poisonous also. That explains the bright color. It's called "Warning Coloration" and it's a reminder to birds that this is not an insect they want to eat.
