Anything that directly affects your survival can become a superstimulus if exaggerated enough. Birds can become confused by eggs from other, parasitic birds who hijack their nests. The eggs look like theirs, but are much bigger, so they sit atop them even though they belong to another. There are orchids that have powerful scents like a female wasp’s or a bee queen’s, and males mate with the flower, getting covered in pollen in the process.
