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:
- "The overwhelming majority of their sustenance—98 to 99 percent—comes from eating ants."
- "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."
These statements indicate that the caterpillars primarily rely on ants for sustenance rather than oregano plants and that their consumption of oregano leaves is minimal.
