Behavior

Males produce stridulatory songs by rubbing a on one against a on the opposing forewing. Song pattern consists of buzzes and interspersed with short pauses. Females approach male choruses and select mates based on song quality, with the buzz component particularly important for mate choice. Both sexes are capable of powerful jumps using enlarged hind legs to escape . Primarily active during day and evening.
