Hi, gary, and welcome to EvC.
Why the need for evolution if the plant, insect or animal was able to survive and reproduce just fine for millions of years before it was able to mimic anything else?
The issue isn't being able to survive and reproduce just fine. The issue is being
more likely to survive and reproduce. Consider a population of a certain species of beetles. If those who look ever so slightly more like Dick Cheney happen to have a better chance of surviving and reproducing than the ones who don't look as much like Dick Cheney, then the next generation of beetles will have more individuals that look ever so slightly more than Dick Cheney.

Why would a living organism actually make it's survival totally dependant on 1 other species to reproduce....
Not the topic of this thread.

How does a plant know the shape, size, geometry and color of the female wasp and the chemical makeup of it's pheromones since it can't feel the shape, see or smell the female wasp? Heck, how does it even know that wasps exist?
It doesn't. Just that the particular plants that happen to look or smell more like a wasp will produce more offspring than those who don't, so in the next generation there will be more plants that look or smell slightly more like a wasp.

How does a species then morph itself into a copy of whatever it is it "thinks" it needs to be....
The species doesn't "morph itself". In one generation, some will look more like a wasp, others will look less. If the ones who look more like a wasp produce more offspring, then the next generation will have more individuals that look more like wasps. After a few generations, the ones that look more like wasps will outnumber those that don't. As new variations in features arise, some will look even more like wasps -- if those produce more offspring, then the next few generations will see this population look even more like wasps. And so forth.

How does the insect know that birds will not eat bird droppings?
They don't. It just happens that those individuals that look more like bird droppings will be eaten less than those who don't -- and so will produce more offspring that, presumably, will inherit those features that made the parents look somewhat like bird droppings.
