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 night when present in an area where the other beetle species is absent. However, where their ranges overlap, 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 nocturnal. The observations above indicate that the two species most likely demonstrate which of following ecological processes? You have discovered an example of ________.
A) mutualism
B) character displacement
C) Batesian mimicry
D) resource partitioning
