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 degrees and one of the second type may retard it 200 degrees .
雪树蟋蟀通过对邻居的鸣叫做出反应来同步它们的鸣叫。如果一个邻居的鸣叫先于它自己的鸣叫，那么一只蟋蟀会缩短它的鸣叫和随后的间隔。如果它跟随自己的鸣叫，它会延长它的鸣叫间隔，有时也会延长下一次鸣叫。第一种类型的单一反应可能会使它的鸣叫相位提前 160 度，而第二种类型的反应可能会使它的鸣叫相位延迟 200 度。
