Are green inchworms poisonous

I wouldn't give inchworms to leopard frogs. Leopard frogs need mealworms, waxworms, earthworms, or crickets. Inchworms aren't required to be fed to leopard frogs. So, I wouldn't take a chance. If your leopard frog accidentally ate an inchworm, I think it may not hurt them. Although, you may want to ask a vet, or the pet store you bought the leopard frog from for a firm and final answer. If you found your leopard frog in a pond or creek, find out which local pet store sells leopard frogs and ask.
