Acoustic Synchrony: Two Mechanisms in the Snowy Tree Cricket

Thomas J. Walker 1

1 Department of Entomology and Nematology, University of Florida, Gainesville 32601

Snowy tree crickets synchronize their chirps by responding to the preceding chirp of their neighbors. If a neighbor's chirp precedes his own, a cricket shortens his chirp and the following interval. If it follows his own, he lengthens his chirp interval and sometimes the following chirp. A single response of the first type may advance his phase of chirping 160° and one of the second type may retard it 200°.
