A high-pitched "tink" (Ibanez et al 1999).
Behavior and communication
Rather than jumping, Diasporus diastema will flatten itself against a leaf and slowly scurry away if disturbed (Scott 1983). Courtship and reproductive behavior were described by Ovaska and Rand (2001). Males approach females as they enter the male's territory, and the two engage in a series of ritualistic behaviors including leg waving, vocal sac touching, and bumping into the female (Ovaska and Rand 2001). Once the female has laid eggs, the males guard nest sites (their territory), but do not attend the eggs (Ovaska and Rand 2001).
