Probably very hungry. They might not recognize the orchids as food. Many might die. I do not know anything about the relative nutritional value of cactus and orchid flowers. That would determine if a low surviving population would continue feeding on the few cactus plants or if the survivors would learn to eat orchids and thrive ultimately. That would not happen in the first month anyway though.
