I found 5 of these saddleback caterpillars, Sibine stimulea on my Zebrine Banana on Sunday. They will sting you real good, just ask Meg. Meg sat on one once and another time touched one on Eastern Redbud by mistake. I have found them here on redbud several times, it grows like a weed here. Those horns have a venom and the pain can last for days so please stay clear of them when ever possible. These are about 3/4 inches long BTY.
Below is an Gray Hairstreak butterfly on cantaloupe blossoms from our garden. I had the tiny camera one half inch from it for 3-4 minutes to get this photo, sometimes they do pose for you, it never flew off either.
