Zahira and the Fireflies

(Sounds like a childrens' book title...)

Lots of fireflies outside tonight. Zahira's never seen them before. They must be destroyed! She runs around the yard snapping them out of the air. Fireflies obviously don't taste very good, because her lips are curling in disgust when she snaps them up. In the gloaming she ends up with quite the Hound of the Baskervilles effect, with a glowing mouthful of teeth.
