When you learn more about plant species you are able to tell when something is different. While driving (slowly) I noticed something “odd” about this Spanish needle flower and sure enough there was something “odd”.
The Wavy-lined Looper, Camouflaged Looper, Wavy-lined Emerald (Synchlora aerata)

Camouflaged Looper | February 28 | Alice Mary Herden
A very unique caterpillar indeed. These caterpillars collect pieces of flowers and/or plant material and use that to cover their backs (hence the name), which would be very cool to video. This is caterpillar for the Wavy-Lined Emerald Moth.
