Ask Mr. Smarty Plants

First of all, you don't say whether you want the plants for food for these animals or for habitat in a terrarium or other container.   Either way, we don't know what the native food plants are for these animals nor what sort of vegetation one would find in their native habitat. If you are looking for plants only for habitat for these animals, you need to research their native habitat and determine if it's moist, dry, sand, clay, loam, etc.  You can then do a COMBINATION SEARCH in our Native Plant Database for plants native to Indiana by choosing "Indiana" from Select State or Province option and then entering other choices that would reflect the size and habitat characteristics for appropriate plants.  If you are looking for food for these animals, you need to do your research to find out what they eat in their native location.  If they do eat plants and you find the botanical names of the plants, you can search in our Native Plant Database for plants in the same botanical family and perhaps you can even find ones in the same genus. 

Determining if any of these plants would be toxic for your animals is going to be more difficult. There are many databases that list plants toxic for humans, agricultural animals and pets; but there are few, if any, sites that discuss plants that are possibly toxic for insects—especially with the view to keeping the insects safe.  Here is one that talks about ways that plants defend themselves against insect pests:

There is more information about toxic plants for reptiles and amphibians.  Here are several that list toxic and non-toxic plants for reptiles and amphibians:
