We undertook field work (aural and visual surveys) and a literature review to obtain information on the biology of the Green-thighed Frog including the location and timing of calling events, the types of ponds used for calling and aspects of tadpole biology. Calling occurs from September to April and is strongly dependent on rainfall events. Chorus size ranged from 1 to over 100 males. Fifty eight percent of records (n = 45) were of 2 to 10 males. Calling at a site did not exceed more than two consecutive nights at a time (11 occasions) and usually lasted one night (20 occasions). Calling sometimes occurred once per season per site (36%), often did not occur at all in a season (26 occasions) and was heard three times at one site just once. Calling was sporadic and unpredictable, usually occurring at only one or two of the Bulahdelah sites on any given night. Calling and breeding was almost exclusively confined to natural or artificial ephemeral water bodies. Clutches are laid as floating rafts and embryoes hatch within 24 hours. Tadpole metamorphosis occurred in 40 days or less, or took over 100 days. Most calling sites occur within forested habitats. The Green-thighed Frog may cope with some land disturbance, for example logging or partial clearing, but it appears likely this species has suffered historically from clearing and will continue to do so.
