The two pieces of evidence from the passage that support the connection "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 pieces of evidence indicate that the caterpillars do not rely heavily on the oregano plant for nourishment, suggesting that their impact on the plant is minimal.
