Gliding frogs eat small moths, slugs, worms, spiders and other insects. Unless you want to keep those around the house, offer your frogs crickets, mealworms, earthworm pieces, waxworms and non-hairy caterpillars. Set the terrarium up vertically for these climbing frogs. When kept in very large outdoor cages, these frogs are capable of long, descending leaps from elevated surfaces.
