The two pieces of evidence from the passage that support the connection are:
- "From an evolutionary perspective, Thomas and Barbero say that the Large Blue butterflies gained an advantage by using scents to glean which oregano plants are fighting off Myrmica invasions."
- "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 sentences highlight the relationship between the Large Blue butterflies and Myrmica ants, emphasizing the adaptive advantages the butterflies have evolved in order to interact with and benefit from the presence of the ants.
