Within each sequence the syllables are grouped into a characteristic rhythym. There are usally 3-5 groups, each containing 1-4 syllables; the groups are separated by intervals of about 400-800 ms, and within each group the syllables are separated by intervals of about 60-120 ms. Each 'tick'-like syllable is produced by a closibng stroke of the fore wings lasting about 6-10 ms.[1]
