The males turn a golden yellow during mating season. The season stretches from April to September on Okinawa.
The eggs are laid in slow moving and still water sources. The eggs will develop into tadpoles and eventually transform into baby frogs. I often find tadpoles thriving in farming water buckets.
The summer months provide a great opportunity for natural predators.The frogs come together in a large numbers.
If you see frogs, there is a possibility that snakes are near by. The snakes patiently wait for frogs in drainage ditches and still water sources. The Kajika frog is the Hime habu’s favorite meal.
