Answer 1

Answer:

Behavioral isolation.

Explanation:

It is an example of behavioral isolation because it is a mating ritual that only this species of spiders recognize. In other words, there could be another type of spider near the web, but only one of the same species will tap the web in a particular way to initiate a mating ritual.  

Different spider species can reproduce, but they do not do it. The reason is that they do not recognize the mating rituals of other species.
