I'm looking into adding more variety to my frog and monitor lizard's diet. I currently have cultures of dubia and Madagascar roaches, wax worms, tobacco hornworms, superworms, and canadian nightcrawlers. I've asked in a previous thread about Pachnoda marginata larvae, but what I'm now finding is that they are not available in the USA.

What other invertebrates are there that would be decent feeders for larger frogs (ie. Pyxicephalus adspersus)?

Thanks!
