The two pieces of evidence from the passage that support the connection that Large Blue caterpillars do not pose a significant threat to the oregano plant are:
- "Large Blue caterpillars only gain 1 to 2 percent of their body weight by nibbling on the oregano leaves during the early stages of life."
- "The overwhelming majority of their sustenance—98 to 99 percent—comes from eating ants."
These statements indicate that the caterpillars are not heavily dependent on the oregano leaves for nourishment, and therefore their impact on the plant is minimal.
