Nudge the clock "forward", not increase speed. So the overall frequency will be a little higher, but it won't keep on increasing

  Exactly. For anyone having trouble, just picture a pure sinusoidal signal, flash = sin(2π·freq·time + phase). Fireflies are changing their phase, not their frequency. Completely independent parameters.

    So the frequencies of the fireflies need to be pretty close to the same. How close are they actually?

      No. The fireflies are able to adjust both their frequencies and phase differences. If their frequencies are matched they are phase-locked. If their phase difference is 0, then they are also synchronized.
