Mayfly is very strict about her space. When she spotted Hailstorm and Winter looking into her office through the window, she snapped at them, slamming a stinky jar in front of their faces to drive them away. She is also intelligent, taking the job of a doctor and giving professional delivery of Kinkajou's condition to Moonwatcher.
The Jade Mountain Prophecy
After Kinkajou was attacked by Chameleon in his powerful NightWing form Shapeshifter, her friends sought out a doctor in Possibility. Qibli asked Meerkat for directions to someone who could help. Upon hearing the name "Mayfly," Winter doubted a MudWing's ability to help, thinking that there were not any MudWings smart enough to be doctors. Qibli and Meerkat reassured him that she was the best doctor in Possibility. After seeing Kinkajou, Mayfly was doubtful that a dragon could have caused the RainWing's injuries. She eventually accepted their story and took Kinkajou and Moonwatcher inside her workplace.
While the others were waiting outside, Hailstorm overheard Mayfly telling Moonwatcher that she initially thought Kinkajou was an IceWing, as her scales were white. He stuck his head through the window, retorting that Kinkajou looked nothing like an IceWing, and Mayfly angrily snapped at Hailstorm and Winter for blocking the light, placing a foul-smelling jar on the windowsill for emphasis.
- "Get out of my window! […] Stop blocking the light! Shoo! […] Go sit in the garden!"

- "Are you sure? […] She wasn't hit by an avalanche? Or thrown off a cliff? Or trampled by a herd of hippos? That really happened to a patient of mine once. There's no shame in admitting it. Hippos can happen to anybody."
