Quick! What's my favorite color?
Bet you guessed red. It's actually light purple. Like lavander.
So why red? Red is short for my college, the University of Redlands. Aside from this, a red dragonfly forms a much better image than a purple one. There's even a Japanese song about it. "Aka Tombo."
The dragonfly part was actually born from my enmity for a rival insect... the butterfly. Yes, I'm one of the rare few people terrified of butterflies. Or perhaps disgust is another word. Butterflies fall apart too easily. One year, a Monarch migration hit California while my mother was driving down a mountain pass. I still remember those orange and black butterflies smacking into the windshield.
Dragonflies are sturdier. And their name evokes far-off lands. Well-suited for a fantasy writer, I'd say.
