Question

Quizplus · Accepted Answer

The Woodland star flowers likely abort flower heads with Greya moth eggs in geographic locations where other non-flower-feeding pollinators are present because the costs of having the moth pollinator outweighed the benefits. Therefore, selection favored an antagonistic response from the plant. This means that the plants have evolved to prevent the moth from laying their eggs on the flowers by aborting the flower heads, which also prevents pollination by the moth. In locations with other non-flower-feeding pollinators, the benefits of having these pollinators could outweigh the costs of losing the Greya moth as a pollinator.
