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 do not rely heavily on the oregano plant for their nutrition, suggesting they do not significantly threaten its health.
