Sound spectrogram of 2 s of calling at 24.8°C (from WTL685-9a). Dominant frequency 6.1 kHz.
Song at 25°C: Brief chirp repeated at 0.5–2 sec. intervals. Chirps have 2–3 pulses at 40 p/s. Carrier frequency drops more than 1 kHz at lower temperatures.
Identification: Length 17–21 mm. Ocellar diameter less than distance between lateral and median ocellus; conical projections at each ocellus; some bristles longer than 0.1 mm on head behind lateral ocelli. Facial pattern varies but if there is a median light area it does not reach the epistomal suture. Stridulatory file has 110–130 teeth.
Similar species: (1) False jumping bush cricket (O. luteolira)—no conical projections at lateral ocelli; stridulatory file has 66-82 teeth. (2) Keys bush cricket (O. diplastes)—no conical projections at ocelli; stridulatory file has 125–145 teeth.
Habitat: Mangroves and subtropical hammocks.
Season: Probably year-round (records are for Mar.–Aug. and Dec.).
