Abstract

Abstract High-speed sound-synchronized photography showed details of stridulatory movements and their relation to the sounds produced. Closing movements were more prolonged than opening movements and generally produced more intense sounds. Wing closures varied in rate from 10 to 250/sec. Four species had unpredicted complexities in their stridulatory movements: one silently snapped its wings shut after each acoustically effective stroke; two alternated long and short wing closures; and one made repeated groups of 4 to 9 progressively changing closures.
