The two pieces of evidence that support the connection are:
- "The overwhelming majority of their sustenance—98 to 99 percent—comes from eating ants."
- "But if butterfly larvae tried to trick the wrong patsies—non-Mymirca ants—they’d likely get eaten."
These selections emphasize the reliance of the Large Blue butterflies on ants, particularly Myrmica ants, for sustenance, and highlight the risk associated with targeting the wrong ant species.
