14 s of calling song [1.22MB]; male from Lake Co., Tenn.; 25.0°C. (WTL686-26a)


Sound spectrogram of 2 s of calling at 25.0°C (from WTL686-26a). Dominant frequency 5.1 kHz.

Identification:    Length 15–20 mm. The only species of its genus in most of its range. Where it overlaps with the false jumping bush cricket ( O. luteolira ), it can be identified most reliably by song and season. Stridulatory file has 70–85 teeth.

Habitat:   Broadleaved trees; occasionally in herbaceous undergrowth, shrubs, and pine trees.

Season:   Aug.–Oct. (Ind.), July–Dec. (La.) Throughout its distribution the jumping bush cricket apparently has but one generation a year and overwinters as eggs.

Song at 25°C:   Loud, clear chirp repeated at irregular, 1.5-3 sec. intervals. Difficult to localize. Chirps have 10––18 pulses at 55 p/s. Carrier frequencies decline by more than 1 kHz at temperatures below 25°C.

Similar species:   False jumping bush cricket ( O. luteolira )—no distinguishing morphological features; chirps shorter (0.15 sec.) with fewer pulses (4-9) and faster pulse rate (71/sec.). Where O. luteolira and O. saltator occur together, O. luteolira is most abundant in well-drained, open woodland and has two generations each year with adults numerous Apr.–June and mid-Aug.–Oct.
