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."
- "And though Myrmica might lose individual battles to the butterflies, the ants are invasive enough that their total populations aren't at risk of being harmed by the butterflies."
These pieces of evidence indicate that the caterpillars' impact on the oregano plant is minimal and that the ant populations are not threatened by the presence of the butterflies, implying that the relationship is not significantly detrimental to the oregano plants.
