Caterpillar survives violent removal and moves about as if nothing happened

Walking to work is fine but what if you have to pick up hitch hikers?

After I settled in my seat, I felt something on my neck. I scratched vigorously and this caterpillar flew off and settled on the faux woodwork.

One would expect such delicate things to be crushed by such force. Nay, nothing like that happened. This plucky creatures are pretty strong. I guess garden lizards find them like we find murukku.
