In the right conditions, frogs can be found out hopping in their hundreds, including on the roads.

Nick Clemann, head of the threatened fauna program at the Arthur Rylah Institute, said there were typically a lot of frogs on the move in the warmer months, particularly in wet weather.

Mr Clemann said frogs’ moist skin meant they were susceptible to drying out and even dying in hot, drier weather, so took the opportunity to get on the hop when it rained.

For many species, summer is breeding season.

Males will call out to females, putting females on the move as they seek out their prospective mate.

Trent Gibson, environmental asset manager at the North Central Catchment Management Authority, said January and February in particular were the key calling times for many species.

Mr Clemann said the Bendigo area had some species that were prolific breeders, with some females able to produce up to 4000 eggs at a time.

After these eggs hatched and the tadpoles matured into frogs, the young amphibians would often have to disperse, he said.

Mr Clemann said frogs might be found on the road in the rain because they were simply moving between breeding spots.

He said they might also be attracted to the roads after dark because the road surface remained warm after the air cooled, ideal for an animal that relied on external sources to regulate its body temperature.

Roads also provided good eating for frogs, he said, an easy surface on which they could forage for bugs.

Mr Gibson said anywhere water was to be found - including drains and irrigation channels - so too were frogs.

He said that while some species were more sensitive and selective about their breeding spots, others would breed almost anywhere.​
