With so many of us busy as bees on a daily (and nightly) basis, it is easy to find ourselves overlooking the small wonders in our own backyard. Sure, we notice the unusually colorful migratory birds and chat with neighbors about the raccoon breaking into trash cans, but rarely do we stand or sit still long enough to admire how the littlest species (littlest yet visible to the naked eye, that is) communicate with one another and how we can communicate with them.
- Each firefly species has its own pattern of flashes, discernible by the number of pulses (flashes) and seconds of delay in between.

- Female fireflies will sometimes respond with a single flash of their own, always at a precise interval after the males.
