How To Sex White's Treefrogs

Both males and females call, but only males call by inflating the throat sac. Size isn't an accurate measure either until the frogs are fully grown. Dark throats are another red herring, I have a female with a dark throat, and a male with a light throat, so that's nothing to go by.
I find the most accurate way to tell a young frog's sex is to look at the front feet for nuptial pads. They appear roughly the same time as the males start to call frequently, which is when they are about 2" (5cm) snout to vent length. To be sure, I'd leave it until they are 2.5" (6cm) SNV.
So, this is how you do it. The nuptial pad is a brown patch on the inside of the thumb of the male, which is totally absent from females. It's present all year round, though it's darker during the breeding season.

First of all, here is my big female

This is what her thumb looks like, no nuptial pad

Now here is a male, you can already tell because his throat sac is inflated

Here is his thumb

See the brown area at the base of his thumb? That tells us he is definately a male.

Now, here's a few more examples. Try to guess whether it's a male or female

Frog #3

Thumb shot

Frog #4

Thumb shot

Frog #5

Thumb shot

Incase you couldn't tell, frog #3 was female and frogs #4 and #5 were males

By the way, none of these frogs are fully mature, except maybe the first one there, but as you can see you can tell well before breeding age what sex your White's treefrog is.

Thank you very much and I hope this guide helped you

They are just ordinary CB White's treefrogs. Probably originated from Australia rather than Indonesia, but I could be wrong. I think there might be a blue-phase or two in there as well (though the camera doesn't show it very well)

Just a quick note on how to maybe get your frogs to call so you can see if they inflate or not......

i have a few methods, here are my best 2

1) download a frog call from the net, my male sometimes talks to the comp when i play it.

2) turn on the hoover or similar piece of equipment as he also talks to these.

once calling see if the throat is inflating or not.

TADAH!!!!
