I released the caterpillar in question, I generally put the insects I catch in a ten gallon with a lid and some turnip/collard greens and a cup of grain. The reason I'm so into this is because of my location and the availability of nice fat green grasshoppers, katydids, crickets, and etc. I do still use crickets and hissers, just experimenting. they are caught from my yard so pesticides shouldn't be a huge issue.
....too bad I don't have anything that could eat a toad, they and the grasshoppers are just plain everywhere since we've had all this rain
