As you study two closely related predatory insect species, the two-spot and the three-spot avenger beetles, you notice that each species seeks prey at dawn when they are found in allopatry (i. e., when only one species is present). However, where their ranges overlap (sympatry), the two-spot avenger beetle hunts at night and the three-spot hunts in the morning. When you bring them into the laboratory and isolate the two different species, you discover that the offspring of both species are found to be nocturnal (which might suggest something about whether this trait, foraging time, is genetically based). You have discovered an example of . a. Batesian mimicry
b. Mutualism
c. Resource partitioning
d. Character displacement
