We're feeding Tilly locusts and brown crickets. Going to get her some worms of some sort shortly. Also greens =D I wouldn't know about bredding though :-(
So ive heard fruit flies are pretty easy.....stick some fruit outside your house/apt in a trapping device..the flies go for it..secure it. I believe the flies will start laying eggs on the food.
Roaches (Dubia, Turkishtan, Hissers...)
Crickets
Silkworms
Superworms (Probably should not be an everyday food).
I have found each of these easy to breed, especially roaches and Superworms. You'll want to provide some variety, so dont limit yourself / your chameleon to just one Meaning, dont have an every day food, but SEVERAL choices, change it up each day.
