Well at a state park the other day i was observing the quarry rocks only to find them covered with the tine bright red spiders known as clover mites. they repopulate rapidly and live inside the rocks. There are so many and well noticing them i also noticed that the rocks all over were orange, and close up it seemed to me that this color had come from the many dead bodies of the clover mites. Its a known fact that when squished they leave a red residue that difficult to get rid of. is it passable that the many dead bodies of these bugs is actually coloring the rock formation?
