Description Refer to the detailed description in Swan (1972) . See also Fig. 13 in this work. MEASUREMENTS . See Tables 1 and 2 . Females are larger than males. SONG . Bobilla bigelowi sings at a frequency of 7.5 k to 8 Hz at 27°C, with a pulse rate greater than 20 pulses per second. Refer to the detailed description in McIntyre 1977a . See also Fig. 14 and Table 2 in this work. The high pulse rate (> 20 pulses / s) is the main feature that distinguishes the song of B. bigelowi from the song of B. nigrova . Habitat and ecology Common and widespread in meadows and grasslands throughout New Zealand , including sports fields and urban parks, Bobilla bigelowi is mainly active during the day; it may sing through the night on warm nights only. It is a frost tolerant species; adults often survive winter and may be encountered at any time of the year. Bobilla bigelowi is generally found on ground with a high level of humidity. It forms mixed populations with B. nigrova and with species in the genus Pteronemobius , with which it can easily be confused.
