FIDICINOIDES PRONOE ( FIG. 8 )

Seasonal rhythm. From March to May, end of the dry season.

Nycthemeral rhythm. From 6.25 a.m. to 20.00 p.m. with higher activity at dawn and dusk. A short and low chorus was heard during the night of 24 April 2000.

Calling site and calling posture. Inhabited the upper strata, on primary stems and trunks. Vertical movements of the abdomen coincided with amplitude modulations.

Calling song. The sequence began with a regular succession of 46 ± 25.54 (28–160, 46) echemes (part A). The call ended with a whistle of less than 20 s (part B), which was sometimes omitted at low density. Both parts might alternate without silent periods. The song was sharply tuned with a frequency band at about 4050 Hz. Sounds were made of pairs of damped pulses emitted at 200 Hz. Pulses were therefore produced at 400 Hz.

Behaviour. Solitary, static at low density and mobile at high density. Did not synchronize their calling songs. A male witnessed approaching a female produced only part A.
