Sorry about your frog, I know how much this totally sucks (see the Eurycea lucifuga thread for my situation)

That being said, I don't thing your frog would be sick of eating fruit flies. If it is not eating them chances are he is sick too. Sorry to be bringing any more bad new.

Ebony, you are the expert here on Litoria ewingii. I only know this frog from books and suspect John will say the same. So like it or not, your one up on all of us when it comes to this species.
