Jungle Nymphs

[Truffs1178]

Just ordered some jungle nymphs and some lime green stick insects and I plan to breed them and sell of extras which I don't need. They jungle nymph females are really cool insects and are the heaviest stick insects in the world. I also had the idea of feeding extra ones to my bullfrog since they are huge and could provide a bit of variation to his diet. Do you think these are ok for frogs or are they poisonous? Here is a pic of a male and female, they aren't my ones.
