Don't overlook flies. Smaller species generally cannot resist houseflies. For larger species, blue bottles flies are also available. When my animals are outside (June through September), I would estimate that different types of flying insects - house and blue bottle flies, bee mimic flies, damsel flies, moths, fruit flies, and dragon flies - make up at least 85-90% of my chameleons diet. I would guess that in their natural environments, this would be similar for many species of chameleons. A search for "feeder flies" will reveal an ever increasing list of fly suppliers. Blue bottle pupae can be kept refrigerated for up to three weeks. When ready for use, simply place the pupae (which are like big grains of reddish brown rice) into the cage in a small covered container that has a hole cut in its side. Placing twenty or thirty pupae into the cage this way every couple of days will insure a steady hatch of fresh, juicy flies emerging. I have never worked with a chameleon that wasn't an eager consumer of flies, but I have worked with many that "go off" other feeders when they have choices.
