It is also good reason to remember that most insect pollinators do this important work when they are adults, even if some of them can be voracious defoliators during their earlier, immature life stages. A change in days or weeks since last years pollination, or the time at which pollen is most viable, can indicate this. These are small containers, fringed with hairs, that enable them to transport pollen back to their nests to feed to their larvae, clearly illustrating how intimately the evolution of flowers and insects are intertwined. Many wind-pollinated flowers have long stamens that are exposed to the wind, and the styles of grasses are sometimes feathered to help them catch pollen grains from the air. Timothy grass is a tall, very robust perennial grass characterised by its long, cylindrical flower heads.

Considerations must be made whether you want to focus on self-pollination and cross-pollination. In insect-pollinated flowers, the pollen grains generated are larger in size, sticky, and spiky, which aids the insect in transporting the pollen grains to the pollinator.
