I found four tadpoles in a puddle and have been raising them. They've become frogs, but I'm having a lot of trouble getting them to eat. I've tried feeding them meal worms, ants, and fruit flies. I found the tadpoles at a relatives house and brought them home, so I do not have access to the same insects that they would have been eating where they were born (I don't know if that factors in).They will let the bugs crawl on top of them and show no interest in eating them. The two oldest frogs died after a couple weeks of not eating which I feel very said about. Their two younger siblings have just become frogs. They still have prominent tails but as of the last two days they prefer to be on land. I'm hoping for some advice on how to get them to eat.

The frogs were found in a puddle outside of Blackfoot, Idaho in the U.S. (it's a farming community in the desert). I've been trying to identify them on the internet and the closest match I can find is the Western Chorus frog. However, it isn't a perfect match and it could easily be a different species.

Thanks,
