Demeter Firefly seeks to capture the essence of an early northeastern spring evening at dusk, the smells associated with the kind of magical night when the first fireflies of the year appear. A very personal scent, this was inspired by one of the twin daughters of the owners, who to this day maintains that some of her best memories are of catching fireflies on Friday afternoons on Spring nights, and letting them go on Saturday mornings. And then biological musings: Fireflies are not flies at all, but beetles. They are bioluminescent organisms, meaning they generate their own light. Most bioluminescent organisms glow continuously. Fireflies are the only ones that flash. The flash of the firefly is produced through a chemical reaction of three organic compounds. The firefly†s glow serves two functions, to warn predators it is toxic, and to attract mates. Each species of firefly has its own pattern of flashes that help males and females find and attract one another. Thus, the dance of the firefly is a true harbinger of spring.
