Different species have different seasonal and daily peaks of activity based on their biology and the weather. To increase the likelihood of detecting target species, you should conduct surveys at the time of year and day when those species are most likely to be active and during weather conditions favouring activity.
You may need to confirm a frog’s identity with an expert. For rare species, university researchers may be the best source of information.
These general guidelines are based on the best available knowledge at the time of writing, but you should always seek local information and current literature on the target species, particularly in regard to weather conditions favourable for activity, and then survey during those times.
