The powerful interplay between the effects of bees and caterpillars was also evident in the plants' reproductive characteristics: In the course of their evolution, for example, the bee-pollinated plants developed a tendency to spontaneously self-pollinate
when they were simultaneously damaged by caterpillars.
heterophylla to self-pollinate
might represent a mechanism to cope with unpredictable pollination and ensure the production of seeds.
Tillandsia lotteae is a nice example of a highly ornamental bromeliad that I tried to self-pollinate

Even though tomatoes self-pollinate
for the most part, if you plan to save the seed, it's best to separate varieties by at least 20 feet.
In contrast, plants that only self-pollinate
may be less able to quickly adapt.
