Which of the following types of reproductive barriers separates a pair of insect species that could interbreed except that one mates on goldenrod flowers and the other on autumn daisies that both blossom at the same time?
a) temporal isolation
b) habitat isolation
c) behavioral isolation
d) mechanical isolation
e) gametic isolation

Answer is B, habitat isolation.

Explanation:

Habitat isolation can simply be explained as a situation whereby two insects or organisms of the same species, that have the ability to meet and reproduce could not, because they are living in different habitats.

These different habitats might even be in the same geographical location or area. That is, one insect might be living in or on the surface of the water, and the other living in the soil or the tree. Due to this effect, the insects are unlikely to meet and reproduce.
