I'm going to say that they are Southern because they are definitely more brown. Stretch has some really nice white stripes down his/her back and both sides of the face. If he/she ever decides to come out of hiding and hop up on the open land I'll get another pic and share.
:cute little leopard froglings! It is so exciting to watch them grow and orph into frogs. i wonder are they northerns or southerns? northerns are more greenish, while the southerns tend to be brown/goldish. i'll try posting a pic of my northern, but if it is something different, sorry. good luck with them!
