Ants are carrying bleeding heart fern seeds to their anthill. They stop to nibble something off the end of a seed. When Loretta bends down to investigate, a seed-like pod falls from the branch above her head. The ants take that to their nest, too. What could it be? The branch over her head has no flowers. Seeds come from flowers. Where could this seed have come from? As she watches, a branch starts walking. It must be an insect.

But, insects don't make seeds. Insects drop eggs. The ants take the eggs to their nest, just like the seeds. They even nibble on them, just like seeds. What are the ants doing with the seeds and eggs in their anthill?.
